I've been hunting public land tracts a lot smaller than 6500 acres for a long time without it having to be closed to the public
Not in this area of Dallas or Russell county. The Cedar Creek and Uchee tracts are in prime areas. Maybe some small tracts in Bankhead or parts of the Talladega national forest would be ok but these tracts would be way overcrowded without some type of draw system.
I like the idea of getting a chance to hunt public land where you have just as good of a chance of killing a nice buck as you would if it were a private lease. Less pressure will definitely lead to better hunting.
