I used to be able to pop out bed without an alarm and be in the woods an hour before light. Getting tougher every year to get out from under the covers, but I force myself out when I know the deer are moving. Once i'm out there though, I wonder why I thought it was such a chore. Where else would I want to be!
I have shot more deer in the morning, especially when it is bitterly cold. Deer seem more sluggish. I love nice calm peaceful evenings and have seen more large bucks at this time, just haven't connected with as many. Heck, I'll hunt any time.
