we have the same problem in buffalo tx, just 15 acres, i would usually tell ya its a 100 deer, but ill just say 30, the problem is shooting..hard to get 1 singled out, our shooting lane is only 15 yards wide, so to hit just one takes patience. and when ya shoot, they all run in to see what that was, but never any big guys though, a few nice 6's, but since this place is un-hunted for 2000 acres for the last 20 years , we lettin em grow..it will pay off in a few years.
