Piggybacking on on what Vulture6 wrote, thereis a website out there (biggamelogic.com) where you can enter your trail camera pictures into a "hunting camp" that you draw the boundaries for. You can place your trail cameras location on the map of your hunting camp (by gps or manually) and it will automatically put int he weather conditions/date/time/ etc. for you and you can tag certain bucks and start tracking their movement...I think it's pretty cool. Right now they don't have a whole lot of people that use it, but it's pretty neat.
