I live about 30 miles from the ranch, but have never heard of it...but that's not a big deal...every ranch around here is a game ranch for at least part of the year. I do have a friend that has a place south of Mason and there are plenty of hogs around. If it's summer, hunt the water. If it's winter, hunt in the middle of the day. We've been dry, for a while, but now that the sows have their first litter of the year on the ground they're moving around quite a bit. I've killed 14 so far this year about 30 miles to the north of me. If you're also looking for deer, some people say the free-range deer in the hill country are small...but that's not always the case. It's just that we have a lot...I mean a lot of deer, so most of the ones seen are the smaller ones. I shot an 8 point on a free-range ranch...not a trophy, but still he was 16inches. A week or so later while culling does, we saw another 10 point that must have been pushing 20-22 inches.
But, graybeard's right. You might not see a thing. I've been to my friends place in Mason when we got 4 hogs in one night and I've been when we didn't see a thing. It's just the way it is in the Hill Country...but it's still some of the best hunting around.
