Walking hills 30:00 
Prospect Hill. Intended to walk solo, but ran into JimP on the park road, so we chatted for about 20 minutes, up and over the top, down the south side, and then around back toward the parking lot we usually use for O. Fast pace, and he was talking with much less shallow breathing than I.
Sighting of the day: a guy on a unicycle riding on the paved park road. First one of those I've seen at the park.
