have any of you seen the mix breed? my dad shot a buck last season that had a mule deer body with a whitetail rack. i've heard that the whitetail bucks were more aggresive than the mule deer bucks but i don't know. this may have something to do with it. the whitetail population where i hunt use to be none! now we regularly see the whitetails and very very few mulies. their spreading like wild fire.
