In the area I hunted this year all the bulls leave the first week of September. They head off to where the cows are. The hunting would have been great the last week of August, there were at least four legal bulls in the area, and a couple others that came through occasionally. A week into September they were all gone.
So I certainly don't want the season to start any later. At least next year it's one day earlier, I'm happy about that!
