RE: leaving a pop up blind on public land
Left a stand of mine in semi private woods in PA a couple year back for 4 hours of light left. Since I was hunting the am, and we never see anyone in the woods with us...it would be fine. Well.....one new lone wolf climber down the drain. I never leave a stand on the woods again unless it is well after shooting hours and I am arriving before light. Even then, I know I am taking my changes.
Good luck.
