Guy Hops On The Back Of A Bus As It Rolls Down The Highway

I really wanna know this guys story. If you ever rode the bus or T in Pittsburgh, you know damn well that the machines that collect the ride fare aren't giving you any change. So this guy either A)Didn't wanna drop a $10 spot on the ride B)Had no money at all or C)Is just an adventure seeker getting from point A to point B.
