I don’t live in the areas of Texas where these things run wild, but I know from people who do that there are huge numbers of them here. A few years ago a friend of mine driving at twilight time drove her truck into a herd of them, killing 4 or 5 and doing a fair amount of damage to the truck.
Which part of Texas is free of ferals? I've shot them along the Red River, on the south side of the state line, when they came down to the bank about dawn. These killers were near Houston.
In the Big Bend?, or the Panhandle?
