Wow ! I stumbled upon this on you tube. Excellent footage and coverage. Not a lot of triples, but some great pro-stock, funny bike and all the comp classes. Very little super eliminator (didnt find any of my races, but they are showing mostly only final round for SE. I never made the finals at a national event) But it was neat to see some of my goods friends who I still see to this day. Some very good footage and racing, enjoy !
