Any public hunting area is a good place to make sure that you wear plenty of hunter orange.
Also make sure that you clear your target and downrange from it before you shoot. For some silly reason bowhunters love to let other hunters walk past them when they are in a treestand, without letting them know they are there. This becomes a problem when the other hunter is squirel hunting and then one runs up a tree.
I have to chuckle a little bit about the numbers, Although it's true that there isn't really going to be 1 hunter every 11 acres on ft. polk. the hunter density is still pretty high. I remember hunting Ft. Meade in maryland, on opening day of gun season the hunter density there was right at 1 hunter per 5 acres. There were places you could go to where it looked like hunter orange flowers were growing out of half the tree's in the woods. (maryland is notoriously shy of public property for hunting) It didn't take me long to find some private land to hunt up there.
Be safe... have fun
