I used to fly at a field that was union property. We flew control line on one part, boaters ran model boats on the lake, and outlaw RC guys would barbecue, drink, run cars on the parking lot, and fly junker airplanes. Things had organized themselves such that the activities did not conflict and I never felt endangered by drunken RC fliers. These guys were AMA members. They would go to the AMA field in the morning, fly, and have donuts and coffee. Then come over to the outlaw field to drink and fly. The union people were glad to have us as our being there had cut way back on their problems with vandalism.
