RE: When to hunt in Maine?
I'd recommend the 1st to 2nd, then 2nd to 3rd...depending on how you like to hunt. The pre-rut is ending right around the 1st week and I firmly believe that the 2nd week always has a few days that are 'hot' so to speak, where bucks are as active as they will ever be.
The deer are also less spooked during the 1st week, not that many hunters out and no hunting pressure on them yet. Either way, 1st, 2nd and 3rd are good. We go the week before thanksgiving every year banking on colder weather. By then the bucks are teamed up w/ the does and have to locate the deer to find a buck.
