I hardly doubt one ranch is solely responsible for the infestation of hogs in your area.
Strange that there was no wild hogs in that part of OK until U Ranch started buying hogs and turning them loose all over the place. Saw the first hog on our place in Garvin county in late 2006. Now they are all over the place and the deer are getting scarce.
When the hogs come in the deer leave. Given a choice, deer do not like to drink from a pond that hogs frequent. i've watched hogs run deer off the game plots and away from feeders.
Most of my hog hunting is done in Comanche, Cotton and Tillman counties. Last year i shot well over 40 wild hogs last year and trapped more while working full time.
