Whitetail are an issue. They'll outcompete mule deer bc they're just wired to be more aggressive. Having said that mule deer are moving into low density WT country here. It's mostly a mix of dry land crop fields (cotton/milo/corn) with pivots scattered all over the place, but I've dove hunted up there for the past 20yrs and just started seeing them in the last 2 yrs. I'm thinking the massive fires a cpl years ago pushed them further East.
