There is another place you may want to check into. http://WWW.BOWSAFARI.COM. They have some damn big hogs. I have several friends that have been there and all have had very good things to say about it.
As for the Shiloh Ranch, I have heard very good things about it too. I have hunted hogs at 6 different places and I will tell you hogs will not come up to you. I have told many people that I think hogs are smarter than deer. Dont laugh. I have hunted them on a 40 acre place 1 time and those hogs were harder to get on to than the ones I hunted on a 5000 acre place in Texas. Something about them wanting to stay alive makes them hard to hunt.
