Well, my wife and I went to Bass Pro Shops today and picked up some miscellaneous gobbler gear. I'm new to calling, so I picked up a variety of calls, including a M.A.D. Calls Shipwreck 2 diaphragm. Unfortunately, I got off to a slow start figuring out how to get a good seal and make it work right.
After some frustration, I gave it to my wife to try, and she starts yelping these really high-frequency notes. I can't believe it! I've definitely found my calling partner.
