For the life of me, I do not understand why anyone would use an unsupervised range open to the public. You are asking for trouble.
Those are both the best possible ranges and the worst ones. It is all I try to use.
I do not like being around others I do not know in such an informal place shooting firearms, however I love the types of shooting I can do. With nobody else around there is some areas you can practice all kinds of tactics. From firing on the move, firing while approaching, while retreating. Penetration tests of various materials. Using 3d objects to test the performance of various rounds on real life materials and getting a more reactive target at the same time.
There are a lot of bad reasons to pack up and leave and avoid them at some times, and some great reasons to enjoy them other times.
You think that is bad. I know a range that is essentialy a lot of high hills about 15 feet high in all different directions with pull outs in various spots. People can end up shooting towards eachother, over eachother, and at 90 degree angles from one another. There is no line of sight to eachother in many areas, and big mounds of earth in the way, but something is just wrong with bullets going by over your head, even if it is 10 feet over your head
It is hard to picture if you have not been there, but essentialy it is very hilly terrain with tons of mini ranges in seperate directions, occasionaly some of those directions cross over parts of other mini ranges, but have big earthen hills and different elevations seperating them.
A scary place to say the least. Most of the time people arrange themselves so they are not pointing in the direction of other shooters even if they are behind such a hill, but every time a new arrival drives down the road and arrives you have to be concerned how they will set up. With steep canyons, bullet drop, richochets off rocks (heard quite a bit) it is a gamble each time you go. Absolute madness on the weekends.
Used to teach some NRA firearms classes but most people are not really trainable anymore. I still do the occasional one-on-one (for free, no less) but it's rare. Even so--I once spent some time working with a young man and thought I had gotten across to him. Then went out to the public range one day to find him shooting his shiny new Ruger P90. The part that really impressed me was when he twirled it. He didn't notice me. I just left.
There is a catch 22 with the enjoyment of arms. Many hobbies you can enjoy yourself and actualy benefit by limiting who you make aware of them, locations you enjoy etc.. It keeps the hobby limited to the few interested enough to learn it on thier own, and laws and regulations restricting, formaly structering, or banning your enjoyment are not quick to form to deal with numerous idiots.
Shooting however is different. The antis are always out in force trying to restrict and ban new things and you have to encourage the use of arms to encourage widespread acceptance and enjoyment of them so there is more opposition facing the antis. So you have to increase the number of idiots (and non idiots) with guns or have your own right lost as the antis gain ground facing limited opposition. It is really frustrating.
