I get to hunt a 5000 acre low fence place near Laredo and a 2700 acre high fence near Freer. Neither is a guarantee, but I get an invite most years to one or the other.
Neither have stocked deer, just supplemental protein and corn for the natives.
I have not seen any variance in the behavior of the deer between the high and low fence places. If you make noise, they haul boogie away from you, and you hunt with the blind windows closed if temps will allow. Both try to have the blinds at least 150 yards from the feeder pen, further if possible.
