I am thinking about going to this event and am wondering if anyone has attended it in the past. I am wondering if being there on friday is necessary or if I can just show up on saturday and miss the friday time trials? Are time trials just like a test and tune or something? sorry for my ignorance, pretty new to racing. Also what is a .500 full tree? they will run that for all the classes. How does one cut a good light with this system?
