I grew up out in the sticks, so my range was pretty much our back yard. Lots of good hunting opportunities as well. The nice big bank on the side yard made for great clay shooting.
At the last place I lived, I had a pretty decent DNR operated free outdoor range to go to. It had a pistol and rimfire range and a rifle range. Like you mentioned though, it also had plenty of whackos and ****-heads that don't pick up after themselves. There was no range safety officer or anything like that either. Every once in a while a DNR ranger would stop by and chase off the people acting like goons or shooting non-paper targets. Sometimes the local 2A club or other volunteers would come out and pick up all the garbage that was left on the range. Sometimes the DNR guys would have to come out and do it, which they really didn't like.
Where I live now, I'm a short drive from a nice outdoor range, although this one isn't free. The range is very nice and clean, there is a range officer to kick out goons, etc. You get what you pay for, I suppose. There are a few other ranges around, both indoor and outdoor, but I've never been to them because of their ludicrous prices.
My preferred place to shoot is somewhere I can go for some no-BS shooting where I'm left alone for the most part. I want to send some lead down range and not have to deal with muzzle-sweepers, brass vultures, gangsta wannabes, etc.
