It's suprising how much ranges and their clientele differ. There are at least 4 ranges within 20 miles of me.
The private range I went to until Ike forced me to move and wiped out the range was generally very empty and well maintained. I could go out on a Sunday morning and have the place to myself or a few other people unless it was deer rifle sight in season. The only thing I didn't like about it was how many people weren't really friendly and members did really stupid crap when no one was around. People shot a pole mounted electrical transformer once, the porta potty was riddled with holes, and I found all kinds of stupid stuff on the plinking range like bowling balls, metal plates, etc.
The range I go to now is generally more crowded and downright overcrowded during dear season. It's a public range run by the city and is clean, very well maintained, and has RSO's on duty at all times. People are generally really friendly. Usually I get to try out something new everytime I go out. Having to weait for the regular cease fires annoyed at first, now I just use that downtime for chit-chatting, smoking/coffee drinking, and checking out what others are shooting, etc.
I've been to two others. One is a huge private range that was nice and clean but heard that its a madhouse on weekends. Too much of a drive for me ATM. I went during the week and saw 2 other people.
The other was a private range that was just filthy. Muddy, standing water, targets were shot to hell with boards hanging. It was mobbed and cease fires were few and far between since the person that called them was busy working the counter checking the steady flow of people in.
The most fun range I've been to was a public range at a state park in Alabama. Facilities were almost nonexistant. No bathroom (other than the trees), no targets (bring your own), maybe 10 firing tables. People out there were always friendly and well behaved. We always met new people, tried and let others try whatever guns were out there. Lots of different people out there from Mountain Men to Professionals with their young kids to college students.
Generally, I don't shoot quite as well when there are others around, but the trade off in terms of social interaction is worth it to me. The only time it really gets to me is the deer hunters with muzzle brakes. Way too loud and the blast is kind of annoying if you're to either side of them. Maybe I just meet all the losers, but their owners are usually as annoying as their rifle.
