Got up early to hike the radio towers and then head for the summit nearby. I thought that was the high point, but it turns out that the high point is a little ways further south and has a flag on it. The point closest to the radio towers is called Casa Grande 2 on the maps. Silly. Anyway, I headed back down the Bolt Trail, which seems like it is really only set up for uphill traffic. No markers, etc. for the downhill direction. A nice change, though, from the road walking of the Radio Tower Trail.
