I have not personally, but have known several people who have. Basically, it is 3000 acres surrounded by a high fence, packed full of all sortsof game. (Cold Brook) The other place you speak of I cannot comment on.
To me, its not hunting, to others it is.
Everyone I knowwho has gone there has killed a hog though, and they seem to be decent size and decently fun...
Not for me, I would rather go south and hunt there.
