I came back today to do the other half of this circuit. It rained in the morning as I set off, but by the time I got there, it had cleared up nicely.
I parked in the same place and did the same as I did last time; I followed the trail of caches until I got back to the A275, then zoomed up it (4.5 km) back to the car.
A couple of buys arrived today - the stand for the bike that I was hoping would work better than the side stand that I hardly ever use because the bike tends to just fall over. But when I tried to install it, after about an hour I decided that just wasn't going to fit.
Also, the 3w red led arrived, and golly it's bright! And yes, I can drive it from a bike battery via a voltage drop-down board. I also discovered that the wattmeter/ammeter I was going to use to monitor the current, doesn't work unless you give it at least 3.5 volts, and as the red led wants 2.0 to 2.5 volts, I'll have to use a different ammeter.
37 caches done today. Tomorrow, I go to an Aufrauf.
