I try to let my cameras out for 3 weeks at a time and only check them when I think the batteries or the memory card are about out of juice or room or I just can't wait any more. I spray down and wear rubber MUCK boots when I go into the area I plan to hunt. I think the #1 thing guys do wrong is not being patient and always wanting to check out their spot. You'll have plenty of time to see whats going on there when the season opens until then let the cameras do their job by watching your area 24/7 .
