Hey that's not fair, we have exotics here in Maryland too, but their harvest is tightly regulated and hunting season is restricted to the fall and winter. I've been to Texas, and you Texans are crazy (but I like it), On a trip through the hill country I saw hundreds of blackbuck antelope, whitetail deer, Fallow deer, Axis deer, mouflan sheep crosses w/ domestic, gemsbock antelop, Impala, and freakN' Waterbuck (standing in a dry riverbed) etc.
While many of these animals were behind fences (and I don't know the point since their density appeared to be uniform for hundreds if not thousands of square miles), in a couple of locations these animals were clearly free range; and, on one stretch of road I saw road kill whitetail, Fallow, and Axis deer within a mile.
You have so many ungulates, I can't imagine why the area isn't crawling with mountain lions by now...NO, actually I can't imagine why Jaguars haven't reestablished themselves without Federal assistence...NO..NO...actually I can't imagine why African Lions haven't been introduced or gone feral and established themselves...I thought nature abhorred a vacuum.
