There are alot of ranches that are set up that way all over south Texas. To hunt on one of them costs alot of money. Getting a deer lease in Texas at all...its not that bad.
I have my own ranch but we don't manage near like they do. Despite the proximity, we have very different terrain and brush than they do. Down south, if you get elevated, you can see for a long way because tall trees are not very common, deer have to cross alot of ground an elevated hunter can see down into. Further north, the brush thick and nasty and you can't see 10 ft into it as well as having alot of oaks and cedar tall enough to where even from an elevated position, its tough to see.
As far as the show goes, I could take it or leave it. Its entertainment, its a chance to see deer on TV. /shrug
