i havnt read the essay type posts, but why not just speak to the owner of the carpark ,or the police, and ask for a chance, just say like, if we can get our club meet in the carpark on say 4th of each month, and give them the web address and number of the main meet organiser, and they can go there on the 5th and if theres way too much rubbish they can then kick you out, because im sure you guys are good people and respect where you are parked
