Each area is a little different, where I am, western mt and specifically bitterroot valley it is flat ON.. The earliest I have seen it. We had a front push in Monday and it kicked everything into high gear. Cant say if it will last because it is so early but it's going right now. Big bucks running around like idiots, bird dog'n like crazy.
I guess I should clarify big bucks for difference of opinion but we just put a 137 on the ground with archery tackle. There are bigger out there but that's pretty good for here.. Thats the class of deer running around like idiots
Good luck.
