Sorry, rereading that I see where there can be some confusion. A guest may participate on one occasion without being a member. If they come to a subsequent event they at that point must be a member. This typically applies to all trillium events with the exception for the driving schools. There, you MUST be a member as liability insurance dictates that.
It's kind of like a drug dealer, here try it you'll like it..........you try it, you get hooked, and you want more, but now it's going to cost you! LOL...........
