ive had good luck hunting late oct bulls in isolated aspen pockets, and timber ofcourse. they want to be alone. ive been startled by big bulls being pushed out of isolated aspen pockets during deer hunts far to often for it to be a chance thing. good luck. dont be afraid to let an ocasional bugle out, they might not be interested but they do want to be alone and theyll alot of times bugle back letting ya know that that spot is taken. good luck. just a location call.
