lets say this theory is right and the bucks are bedded down before light..... the only problem is that anything can spook a deer up out of its bed. how are you going to shoot a buck under your stand while you're snuggled by your wife when a tree limb, squirrel, etc. kicks that buck up by your stand? this is the way i see it.
there are only so many days to deer hunt and plenty of off season saturdays to sleep in. the deer are always out there. maybe you're not seeing deer in the morning because you have chosen a poor stand site for your morning hunts. just a theory.
