I know exactly what you mean... We have a rock pit nearby that serves as our local shooting range since actual ones are lacking in my area. Great part is, it's free. Bad part is, it's free...for everybody. And completely unregulated. Every single time I go up there, without fail, some new idiot shows up with a crappy Bulgarian AK or Mosin he bought at Big 5 for $80, and tries to strike up a conversation with "Hey man, you smoke grass? No? Well, can I have a beer anyways?" All the while waving his new found $80 toy around wildly. Irritates the hell out of me, that the few good shooting places around keep getting ruined by these tools.
