I think it all depends on the size of the tract but first to the lot should have first choice.
If we're talking a 10,000 acre WMA, you're going to have to coordinate with some folks and that's entirely reasonable.
If we're talking about 100,000 acres, you should politely turn your truck around and find yourself another place to hunt.
Discourtesy runs rampant these days with the popularity of public land hunting and I personally have less tolerance for it than ever. It seems harder and harder for people to do the right thing.
