that's a tough one. i'm not real fond of setting up my climber in the dark, but then again packing up in the dark isn't much better. i'm about equal with morning or evening success, just being in different places at different times. mornings give you a lot more options for the hunt and the opportunity to change it up if you get bored with it and there's no action -stand, stalk, sleep, lol...doesn't seem to be as many annoying bugs in the early morning as the afternoon/evening either. but i love to hunt both, sometimes dark to dark. anytime in the woods is a good time in my book.
