I have hunted private land right on the edge of Hoosier Nat'l Forest, but never in HNF. However, I've talked to hunters that deer hunt there and they say they seeA LOTof birds. Wish I had more info about it, but I know it holds a good amount of birds.

edit: You might also want to look into Morgan/Monroe State Forest, but I don't know what the turkey regs are there..I'd assume its open to hunt just like it is for deer.

Good luck to you, way to stick with it instead of throwing in the towel.
