Dont know if you have found a place but you might try here.

I have hunted here 3 times and have had a great time. Lots of open range hogs. First time 250lb boar, second time 325lb boar, third time sadly lost a larger boar but still had a great time hunting.
If you do get a hunt booked with him tell Ron that Rick in Lubbock told you about him. Might be worth a + for my next hunt. Who knows. lol
Good luck,
Who
