We'd appreciate if you'd register. The event costs a bunch to put on and registration is really the only way to pay for the event. BUT.....NO....you don't have to register if you aren't planning on doing the following....drinking adult beverages, going on organized group rides, participating in the night ride poker run, participating in games, or purchasing raffle tickets...if you're just coming for a day to hang out and see what's up...no real need.
