Around here in Minnesota the bowhunting opener usually opens I think in the 2nd Saturday of the month in September.
I recall usually by opener the acorns are down and we can't take advantage of a mast harvest as an attractant because that activity is done and over with. This year I noticed several white oaks still holding their acorns by opener, except they have been smaller in size. I'm guessing it's due to the dryer summer we've had.
