I like mornings best for having daylight to track and I'm not running out of hunting time because it is getting dark.
I usually see more deer mid morning than first light, and see many more deer from 8-10 than I do daylight to 8.
I have sat a lot from 10-2 and while I have seen deer, not nearly as many as mid morning or evening.
I always think I am going to see the big bucks I read about that were roaming in the middle of the day, but it never seems to happen.
