50F today 0F tomorrow so: last chance for a lunchtime bike ride. I rode up into Hall and got to the quarry when the first snow hit so I raced back down. The lower trail was icy and I slid through a turn and then off a drop and landed well before my bike landed on me. In, as I determined during a cleanup shower, a lot of cactus. It's really inconvenient how much of our bodies we can't see.
But this is why we invented USB microscopes and friends.
