Oh man, you just missed the best part of BCT. My favorite is the point where you turned around to Black Canyon City. I saw rode a week ago and went North, but it is the trail south to the point where you stopped here that is really cool. Although BCT is a great single track throughout.
Oh bummer! I was actually looking to do just a quick ride before I drove back home, but I just couldn't stop! I'll be back at the end of April for the Whiskey in Prescott. Might just have to stay an extra day to check out that next section.
