Then don't pop it. It's simple really. It's not rocket science. 90% of people do anyway. I've never had a issue. People are going to steal regardless so what's it matter.
Not being mean but this meet may not be for you. I prefer you not to waste your time.
That Thursday meet is dead. We are a small group meeting up to eat and hang. We had no issues last time. Matter of fact a cop pulled up and told us to basically have fun. Right before I left I saw another car group coming in. So people meet and eat there all the time.
