    Why does camping in a state park have to be so expensive?

  • Post #4261508

    I was thinking about a 2-night trip, but at $45/night for rustic camping, I&amp;#39;m thinking about just an out and back closer to home.

    A quick writeup of my ride in the Amishland and Lakes event yesterday. https://ohheybrian.com/blog/2026/07/amishland-and-lakes-2026 #biketooter #blog

    Just made a reservation for August 12 at Van Buren State Park near South Haven, MI. The only bummer is that there was a fantastic site available, so I put it in my cart. But then I had to make an account and my cart was lost, but the site was still pending, so I couldn&amp;#39;t re add it. I had to leave for a while and when I came back, someone else had grabbed it 😭 I got one that&amp;#39;s still in a nice spot, but it&amp;#39;s not as good. Still looking forward to my little adventure.

    Today was a very productive day. Work on the new house flew - several windows installed and the old part of the house got prepped for its new windows along with siding tear off. At home, I managed to get the fridge recharged and it is now cooling again (thankfully). I also made big progress on the new seed tray cart - that&amp;#39;ll get finished tomorrow. #today #farm

    Well, the cart came together well, but I need to do some work on the axle. There&amp;#39;s a ton of torque the way it&amp;#39;s currently set up, so I need to figure out a way to have a fork on the wheels to reduce that force.

    Super tired again tonight. Spent the day finishing up the seed starting cart (I&amp;#39;ll post pictures tomorrow) which had turned into an exercise of iterations in engineering. A couple of teardowns and rebuilds took up most of the afternoon. Tomorrow, it&amp;#39;s back to the house build for the morning at least. But for tonight, it&amp;#39;s a shower and a beer.

    Just realized my blog has a bug. If I save a post as a draft and then publish later, the RSS feed isn&amp;#39;t generated. Not sure why ...

  • Post #4261501

    Of course I realize this while I&amp;#39;m eating breakfast getting ready to head out the door. I&amp;#39;ll have to look at it later.

    Trying to decide how far I want to ride my bike tonight...I just mapped out a 23 mile loop, but that is feeling excessive. I may just go for it and shorten it if I need to.

  • Post #4261499

    Ok, I decided to do the full route. https://ridewithgps.com/trips/401597782?privacy_code=bSd5cnhfAAj2g4kEKPv2cAGsyy4Vq5kl #cycling #biketooter

    Anyone with commercial refrigerator repair experience? We have a Continental 3R refrigerator on the farm that has stopped cooling. The compressor runs, but the high/low pressure cooling tubes are not hot or cold like they should be. I&#39;m assuming the thermostat isn&#39;t to blame because the fridge is trying to cool, but cannot. I need some tips on more troubleshooting or options for a repair. This is a pretty critical piece of equipment. #askfedi #diy

    It&#39;s too hot to do anything outside so I&#39;m doing some sketches inside from photos that may or may not be painted some day. #mastoart #sketch #landscape

    Ok Fedi, I&amp;#39;m starting the process of researching solar panels for my barn. I&amp;#39;m a DIY person, so not looking for install recommendations, more interested in what I need to learn in order to do this wisely. Hardware, unexpected gotchas, other things DIY people need to know. I can build and I am comfortable with electrical work. #askfedi #solar

    More enshittification in education this morning. I don&amp;#39;t use Kahoot often, but it is helpful for concept reviews. I used to be able to get high-level reports of how each student did. Nothing wild, just right/wrong ratio and the most missed question in a set. Not anymore. Today I logged in to look at yesterday&amp;#39;s warm up and it&amp;#39;s all behind a paywall now. I can see the top three, but no one who actually needs help. Why can&amp;#39;t we have nice things. #teaching

    Doing acids and bases today, students understand why the general acid formula is HA (A- anion produced). But why is a general base formula MOH? I don&amp;#39;t know what the M stands for...I just know that&amp;#39;s what we use. #askfedi #chemistry

    This is a little concerning - The Lancet published that school phone bans don&amp;#39;t improve student digital addictions, it just offloads it to non-school hours. https://www.thelancet.com/journals/lanepe/article/PIIS2666-7762(25)00003-1/fulltext We have a ban coming next year in Michigan, which will be one thing. I&amp;#39;m already talking with students daily about their phone habits...I need to be more intentional.

    A field and a mountain this evening. #watercolor #mastoart #sketch

    Today in the classroom: I was out yesterday and unfortunately I have to talk with two classes about how to behave with substitute. Pretty ridiculous. First year chem is doing more molarity practice. I might add dilutions in today. Second year chem is taking notes on buffers to prepare for their big buffer lab later this week. #chemistry #teaching :cupofcoffee:

  • Post #1213074

    I got the bottom bracket apart (except the drive side...I need to get a better tool), but the bearings were a mess. How do I size these for replacement? This is a generic kids mountain bike (Dynacraft Magna Echo Ridge model 8153-31Taj) and the manual doesn&amp;#39;t have info. Can I just measure the bracket with calipers? #biketooter #askfedi

  • Post #1213073

    Today in the classroom: Labs all day. First year chem is preparing a solution from solid to a specific concentration. I&amp;#39;ll test with a colorimeter against a dilution series I did this morning. Then, they dilute to a new concentration and check again. Their grade is partially based on their accuracy. Second year chem is exploring properties of buffers. They&amp;#39;ll compare solution ratios to measured pH values and calculate Ka for an acid. #teaching #chemistry :cupofcoffee:

    Took a stack of grading home last night just because I ran out of time during the day. I marked it all and put scores on my clipboard to enter today. Left my clipboard and all the papers at home on my table :eyeroll:

    I told my TA today that I would do dishes because I need a mindless job to distract myself from all the crap that has happened this week.

    We have something like 40 days of school left and the 10th grade boys are falling _apart_.

    A few comments, as a teacher, on the Ars Technica article &amp;quot;To teach in the time of ChatGPT is to know pain.&amp;quot; https://ohheybrian.com/blog/2026/04/teaching-in-the-time-of-chatgpt #teaching

    Today in the classroom: I have written detention referrals every day this week. I am praying that I don&amp;#39;t have more today because I&amp;#39;m worn out. First year chem is finishing molarity practice and doing a final check on solubility at the particle level when things dissolve. Second year chem is finishing their buffer lab - we didn&amp;#39;t have quite enough time yesterday. They&amp;#39;ll describe acid/base salts w/ net ionic reactions and calculate Ka. #chemistry #teaching :cu...

    We also got this monstrosity yesterday. I have many thoughts.

  • Post #1213065

    Balancing out the awful bucket, our kitchen staff have put an extra cooler of food out for students. It&amp;#39;s all precooked with reheating instructions on the packaging. This reduces our waste and feeds more people.

    A couple little landscapes this evening. #watercolor #mastoart

    I&amp;#39;m getting into my own bicycle repair. I&amp;#39;ll start with my daughter&amp;#39;s, whose cranks are sticking. I&amp;#39;m planning on trying to get into the bottom bracket today to check the bearings. This video is fantastically helpful: https://www.youtube.com/watch?v=VXQA4kNmhPA #biketooter
