Log on the Ebay and type in "turkey calls". There'll be lotsa pages but be patient and look until ya' find "papastomtaker call" (wingbones) in the auction. He makes 'em with and without lipstops. He also makes and sells some pairs of 2 and 3 segment calls. They're pretty dang inexpensive and they'll flat shore make an ole Thunder Chicken yodel. Trust me on this one. They led to the demise of 4 gobblers this spring.[:D]
"Chasin' gobblers has a lot in common with dealing with a wife, 'bout the time ya' think ya' got 'em figured out, they change the rules!!!"
