well to me it really depends on WHERE and WHAT I am hunting
if I am hunting over crops or food plots, 99 % of my hunts in the are evenings, as from my experience most deer are long out of them by shooting light in the AM
If I was to hunt say a behind a food plot say inbetween a bedding area and a crop/food plot I would say its a better 50/50 mix of deer sightings
In just BIG timber, again its a bout 50/50 of morning over evening sightings, but to me in BIG woods over the yrs I have seen the most deer between about 10 am and 2 pm
and that goes also for once the rut starts up, in most sits no matter where
where i hunt here in PA, due to NO bedding on the property, mornings are almost useless to hunt, so few deer on the place during mornings
so I base where i hunt on many things, not just the time of the hunt, deer are out there 24/7, so you just have to fond where they are at the times you want to hunt them
Good luck
