Umm, maybe this is a dumb idea and its too late because y'all are already out there... however, wouldn't it be bright to call the cops when these unwanted guests start doing burnouts. Just call the cops and say "hey we're having a car meet and some punk just rolled up and started doing burnouts very close to my car and I don't like it." It would serve two purposes. First, you'd get to actually talk to the police like humans and state your purpose, second, it would scare off the people that are going to start crap if they roll up and the cops are there. What fun is that, right?

Starting fights or so much as making threats will only create bigger problems.
