I am not big on stunts on bikes, but my kids love going there, and every time I go there I meet people who have traveled hundreds of miles to be there. It's a big, big draw for people who like this sort of thing. They have really cool bike tracks where you can do all kinds of jumps, races, tricks, flips, etc. I wish I had the language for it. Maybe just take the kid there once before you schedule a party to see if it's the kind of thing (s)he would like. You have to try it once!
