On Saturday, I rode the main mountain biking loop at Camp Tamarancho. It's also known as "Boy Scout Camp", because the land is owned and maintained by the local Boy Scout Council. Let me just say that, those Boy Scouts aren't playing around. That was a serious trail with a lot of varied terrain. I think it may have been a 9 mile loop, but it could have been a bit longer due to parking far from the start. Afterwards we ate had some beer and brats in lovely Fairfax.
Back in SF, I somehow managed to stay awake until midnight and rode the SF Midnight Mystery Ride for the first time. It would have been wise to use an app to plot both of these rides, but I forgot. The mystery ride started at 10th and Folsom, and wound through the city for about 1.5 hours. Eventually it ended at the Bernal Heights Mini-Park Slides, which is a place that I've read about but never visited.
