GoPro Footage of a Guy Speedflying in Hawaii

I'm not sure who's idea it was to first climb a mountain then jump off the side of it with a parachute and try your best to avoid all the rocks (while at the same time getting as close to them as possible). But that's pretty much what this guy does. Except he throws in flying between two buildings and lands next to a yard guy. Sounds like I'm making this up, right? (Spoiler: I'm not)
