I've seen does swimming the Tennessee river and crossing pretty much every section of interstate I've driven in Alabama. I'm having a hard time grasping how these barriers are preventing the genetics from mixing. Rut dates were originally determined over time by the habitat and climate as well as genetics. Maybe in todays era of micromanaged habitats, some of the rut dates could be affected in small areas. This isn't even a theory of mine, or anything that I've given any real thought to. It's just a thought that just came to mind a moment ago, but right at this moment it makes as much sense to me. The rut timing in Alabama is far to complex for me to take enough time studying it to understand it fully and I think I'll just enjoy hunting whenever they rut and whenever I can get in the woods.
