I go to a fairly remote public range, which has no range officers or supervision. Yes, you have to be prepared to leave if someone doing stupid things shows up. Mostly, everybody communicates and it is safe.
I do take a trash bag or two, and police the area for trash. On my way home I stop to get gas and put the trash in a dumpster (asked the manager, who was a shooter, and he was cool with dumping).
I also pick up a bunch of brass for reloading. Be observant, watch who is using new ammo (once) and when they are done wander over and pick up free once fired brass.
