ONSR is Federal Land and concealed carry was not allowed. Signs went up all around the Current River parking lots when CCW passed stating that no loaded guns allowed on the stream or parking lots. Hunting has been allowed, but only so many yards away from the river, campgrounds, and parking lots. If you were pressed, openly carrying a handgun in the ONSR while fishing could have drawn you a ticket.
Loaded firearms of any type were prohibited in wetlands managed by Federal Fish and Game in places like Mingo Wildlife Refuge. You could not even have one in the vehicle. Guns had to be cased and unloaded.
I don't think you will see Rambo out there, most will be carrying CONCEALED, which means out of sight. You will never know it.
I suppose that most of you have not run across a Meth Lab, Drugged up or Drunken people that want to cause you harm, Feral Dogs, Bears, Mountain Lions, escaped convicts, your truck getting broke into, or someone harrassing your wife at the access when you return to your truck. In my travels, I have come across most of the above except for a Mountain Lion. A handgun has foiled a robbery, changed a few individuals minds about harrassing my wife, killed 2 dogs and who knows what else. My handgun has alway been openly carried, its hard to say how many times it changed the outcome of the persons I have met in parking lots, in the woods, or on the river. I have found meth labs, seen some stashing drugs while Conservation agents were checking for violations, and met alot of drunken, obnoxious people. But for the most part, I carry to have a signaling device if I get hurt while fishing alone. A 22 pistol is great, you can carry 100 rounds of ammo and have something that gets peoples attention if you need to be found.
Keep plugging away over there in Illinois, you may get a carry permit soon. The CCW guys are making good progress in your state too.
