Well, in my opion, you won't find a better set of tapes then these....

Recordings of wild turkeys in the woods. Knight & Hale also make a great recording but I think it's only on C.D. You can check them out along with the Lovett Williams tapes/C.D.'s at http://www.huntsmart.com Click on Turkey then on C.D.'s & Tapes if they still have it set up the same way.

Good Luck.
