To go along with post #35:
Very good info on your particular experience while shooting on the Allegheny Nat'l Forest. I think a whole thread could be started on the NF/shooting subject, state by state, and regulations for each on the Forest. I use the Big Horn Nat'l Forest here in Wyoming almost exclusively for my elk hunting, and deer, too, if the opportunity presents itself. As far as shooting in the Big Horn Nat'l Forest, the regs. go through the various restrictions in some detail, and then adds, and ends, with this:
"In simple terms, this means don't shoot within an area 150 yards of campgrounds or campsites, across a lake, or creek, across, or while on a road."
Hunting, fishing, shooting, camping, hiking and whatever else one enjoys while in the Big Horns are accommodated quite well by our local Forest Service folks (WY, G&F, too). Still, It's always wise to check with any FS office, anywhere, to particular usage questions one may have (IMO). Generally, Forest Service informational bulletin boards are fairly easy to find, too, at least on the Big Horn Nat'l Forest.
