Well, we are all thankful for the generosity of landownes who donate the use of wonderful places to run Dogs. I recall from somewhere that when the freeforall ran in south Mississippi they used about 8000 acres. That kind of ground likely isn't available any more East of the river, but it stl is in Texas and Oklahoma. The bird population isn't as consistent out there tho and is harder to manage.
I still think there is a place for the 3 hour Free For All.
