i have harvested deer both in the am and the pm. but i have a hard time getting out of bed if i am hunting by myself. so i would have to say it is a lot easier for me in the evening.
in my defence i work shift work so i work a different shift every week and am gennerly tired all the time. i cannot tell you how many times this year i woke up saw the leaves blowing a little or saw the groung a little wet and went back to bed. it is ashame because i have an awsome morning stand.
