Yep I agree with all the other guys, I leave my cams out for 4 months at a time (SOLAR)
It's nice to see whats going through the area, like the other guys BIG BUCK the time he got his picture taken was at night which tells you alot about the buck, he is a old timer and most likely says bedded down during the day time and waits until night time to move around, now that this guy knows this he will have a better chance to bag him...
I have seen alot of pictures from my cams which at least tells me what is in the area at that time of the season. It's a good way to keep your pumped until the hunting season comes near.
Also read this mag this is by far the best deer mag I read gives alot of info about how the bucks and does move.
