I'm from the area, grew up near Kingsville and have hunted around Concepcion. There used to be a lot of outlaw hunting and the area was completely shot out as there are quite a bit of ranchitos on the area and all the primos come out on the weekends and kill everything. It really depends on where it is exactly, acerage, and neighbors. If you let me know where it is I can give you a good idea. Feel free to Reply here or PM
Yup, one stop sign town just outside Benavides on way to Kingsville. Always had a reputation for just what you're describing, Benavides and Realitos on the way to Hebronville both had that same reputation in the 1980s-1990s...
