Great tag! It depends on whether you want to hunt early in the month when the big bulls are usually cruising looking for cows to establish their harems or later in the month as the rut actually gets going and they are bugling, chasing, fighting. It's generally easier to call in a good bull before the middle of the month when they're receptive to cow calls and harder once they get cows together. Then it's generally the smaller satellite bulls that will come in. It's also very hard to get within bow range of a big bull surrounded by his cows with all those extra eyes and noses you have to fool. If you can't hunt more than two weeks, I'd pick the middle two weeks of the month. That way you can catch at least part of both in a normal year. Otherwise, I'd go the last half of the month because in a late rut like it was last year with bulls still hard in the rut well into October, you'll catch at least part of it when you might not if you went the first two weeks. In any event, if you can hunt a couple weeks and know what you're doing a 330" or better bull can be had from that unit.
