Hope they are high in trees looking down or I suspect you will NOT find your cameras upon your return to the area. With it being SO EARLY in the year I would check them in a week tops. To be honest, I would check'em in 3 nights. As it's on public land and a new area, you need to quickly determine if it's worth it to leave your cameras there. No sense burning batteries on birds, grass, squirrels, and humans. If you find something that peaks your interest, then I would reposition your cameras and leave the area alone for at least 10 days. IMO, this is enough time to determine if any bucks you like are frequent visitors to the area or just an occasional passersby. Again. make sure you secure your equipment as sticky finger syndrome is unfortunately all to common. Good Luck!!!
