Not my first ride, but my first real mountain biking trip. I discovered something. I no longer have Skillz. Of course, we were riding hills that had 45+ degree slopes, lots of roots, and 1' drops in places. Needless to say, the people i was riding with were just a little out of my league. That, and i bonked, which sucked, cause I hated making them wait at the top of the hills. Other than that, It was great!
