It was all tar paper with sand on it so no tile. The sketchy part was the bottom of the transition that can't be seen was all gravel. About 6-8 feet of fine gravel that I could ride across but wasn't stable. Also would've been fun to jump the street spine but right where the photo ends on the right the roof stops and the drop is pretty far to flat. Went back to shoot again but got kicked out. Oh well.
This shot was back when I was maybe 18 years old, it was a few years back. Head injuries and helmet technology wasn't very prominent. I rode without a helmet throughout a lot of my younger years and learned better since those days.
