OK, I'm no expert here but I've got the NRA Range Books here and I've set up two private ranges for myself and been involved with maybe 6 public and private. It's a hobby with me.
Here's my take.....on top of agreeing with all that's been said.
I'll start by using something else entirely to illustrate where I'm coming from. My first "fun" property I ended up having about 7 acres of rolling land that was being tree-farmed. I was raising kids, riding dirt bikes and quads and Honda Oddyseys and generally enjoying life.... and I have relatives who own dirt moving equipment. One of my cousins contracted to build a "Tuff Trucks" race course at the local fairgrounds. What a BLAST!!! He got free reign to make a course designed to tip rigs over and send them into the tules, jumps and twisty-windys and all sorts of stuff. Needless to say myself and another cousin decided "what the hey!" We both set up courses, just for fun. I mean, what could be cooler than having friends over and being able to do what you want right there???
And fun they were.
Word got out.
Someone nearly got hurt on my track...
Someone did get hurt on my friends track......
We started talking about waivers and sign-off sheets and homeowners insurance and such. I called my insurance agent.
He very nearly cancelled my policy on the spot.
I had my own private range on the same property...... same thing, word got out. Friends of friends of friends. I had to send a guy home because we couldn't find his first round on the paper. Tensions built.
I took the track out, my friend took his out and I completely shut my range OFF except for personal invitation only. My current setup is invitation only, very low key and completely alcohol free, NO exceptions. (((This has always been my informal rule starting back with the bike tracks. As you can imagine this doesn't set well with some people!))) Anyway, I had to come to grips with the fact that in my situation I'd rather lose acquaintances than risk my livelihood and family. My property is set up for Hunter Education so I get asked, a lot. And I've got lots of people bugging me to make it public. I've even got people trying to guilt me into it because my situation is kinda' unique in that I can probably never be threatened by neighbors moving in. I'm removed enough that I can shoot 24/7 yet I'm only 15min out of town..... I keep the range pretty brushy so it doesn't look too inviting.....
Now, here's where I'm gonna' get in trouble.....
...... I'll probably NEVER make it public. Because a lot of shooters are absolute jerks.
People are WEIRD!!
In My Opinion.
I mean, WHY would anyone shoot a sign? Or another mans cow? Or his tractor? Or his barn? Or cut his fences? Or shoot off his electrical wires? Or shoot holes in his irrigation system? Or shoot up the target frames? Or set cans on the berm? Or leave trash? Or clean their gun and leave the patches on the ground? Or leave their targets out? Or just set there and argue with the rules???? etc etc, all things I've personally seen and many more.....
My creed is very simple..... when I'm in another man's house I abide by his rules. Period, end of story. Even if I've rented time in his house that doesn't make it mine. If the sign on the wall says "wipe your feet, keep your dawg in the car and cover your mouth when you sneeze" then that's what I do. If I don't like the environment I don't come back, but I don't break the rules. WHATEVER the Range Rules are they're THE WORD. I don't have to know why, I don't have to know anything but the rules... I mean I'm a smoker fer cryin' out loud but I've never smoked where it's not welcomed.
However I don't find this sentiment everywhere. I find an awful lot of folks just CHAFE at rules. Especially if they've paid their pittance to use the property. If they're not bending the rules they're ignoring them. Or they go off on a spiel about "how it is on THEIR range" over on Ferbegnoggin County......
I quit going to public ranges 20yrs ago because of this. Too many people think that because they're "members of the club" they can do what they want. Or they're just careless and don't take the rules seriously and get mortally offended when someone tries to correct them. Or they abide by the rules for a while but kinda' let them slip over time.... And then there's "the Good Ol' Boys Club" where once't you've paid your dues you get to flaunt the rules. In front of others.
AND.... all that said...... real accidents DO happen, even to careful people.
So anyway, sorry about the (maybe off topic) mini-rant but as one who's really tried to share his passion with others I'll opine that IF I ever decide to get involved in setting up a public range I'll probably either go straight to the local police department and try to get them to involve themselves right from the get-go, make it a "Training Facility" with the blessings of the local bureaucracy, or get so far out of town that errant rounds are a non-issue.
I really hope that whatever you do it turns out to be a positive experience.
I'll suggest that one of the very first things to do is contact the NRA. Educate yourself on the gravity of going public in today's litigious and irresponsible environment. Proper planning is certainly the first step.
