I think we had some bars over asphalt/concrete/cement (I dunno, it was a big solid surface that was also the parking lot, the kickball diamond, the wiffle ball field, and where we had all of our field and track days) but I only ever fell off the ones over the rocks. I do remember friends with broken teeth or busted noses from that, tho.
Ooh, damn that’s rough!
