I use my trail cams mostly for fun. If I don't see any good bucks on them, then I know I've had the camera in the wrong place. I know where not to hunt. Come the rut, bucks will be in random places. They'll show up where they weren't before. Some will come from other properties.
If you see a lot of bucks on the cams, that just means you need to hunt harder. They're there. Whether you see them or not.
