yeah, that was the other fun bit, seeing all the eighties SX spectator gimmick acts - the 'sphere of fear' (with not just two bikes going round inside but their pretty female assistant in there too holding flags which they pluck from her as they spin round and round....), doug domokos wheelying a honda trike along two tightwires, and various stunt riding variations.
evel got em going, and no doubt they all made a buck or two from it - more than they would flogging themselves across a set of gnarly whoops!
