it does sound interesting, I'll try it out, why not. But if you do try and make a 17- speed thing, it should be just a meet up, but definitely make one, it's a lot more fair on those who can't quite participate in the adult activities, but do put a limit on how young it can be, id say the cut off should be 13 as the youngest that can enter, because their at least old enough to wander around (even tho that's still a bit young, I figure it would be easier, because of the fact they have a separate type of badge) But the reason I bring up the cut off for the younger one is because I don't think a lot of parents would approve of their 12 year old doing a speed meet up thing, but I could be wrong on that.
