Every squirrel that snaps a twig or shuffles some leaves keep me awake! I swear each one seems like a deer coming to me! I'm usually up for work around 4:30 a.m. anyways, so being in the woods at 6:30 is no problem. I also don't have any stands to sit down in... I always stand, so falling asleep really isn't an option! Now if I end up getting that ground blind I've been thinking about, those quick cat naps might be nice...
