I went there several times, as it's on my way home from work and open 7 days. Nice folks, and safe but not anal about protocol if you act like you know what you are doing. I had one pistol that was doubling on me. After two instances one of them stuck his head in and asked if I was having problems. I replied I had it handled and he said "OK" and went back. If that had happened at BP they probably would have shut down the whole range and called security to escort me out.
I never saw those seedy characters but that area is not one to hang around in. I figured only an idiot would mess with a guy walking into a firing range.
Last year they started closing at 6:00 so that ended my visits.
