I'd listen to Josh.....
He can JACK you up if you are 1/4 inch over the line.....
Fricking cops.................
People shoot in the sandpit off sandhill RD a lot I'm guessing that is what you are hearing. I do not know who owns the land down there but it is easy to get to The trail is right off the road and follows the powerlines. Another place that you might want to look into is John Collins's sand pit up off Buckhollow Rd, of course you would have to stop and ask John or Betty first. I believe Alan Simoneau is the one who has a range up off fletcher Rd but I don't know if it's open to the public as I was pretty sure it was only for competition shooting. I know he has competitions up there and they do all long range shooting like 300-800 yards.
