Get some sponsors for a calling contest at the end--three categories just like a NWTF event. Give away prizes to the top 2 or 3 in each category--the best one I went to broke the categories up into friction, mouth, and locator calling. Then the top caller from the Advanced (which was a term for elderly--anyone over 60), Experienced (18-60) and Youth received a prize.
Bring your calls and camo. Demonstrations keep an audience on edge and active. Ask for volunteers for group demos. Bring SHORT videos and live audio tapes.

Some of the best advice I received was what to do with the bird AFTER the kill. Much is covered about setting up, calling, etc.--but hardly anybody tells newcomers how to dress and transport the bird home, clean & package and finally cooking. A good way to end the seminar before the calling contest, gets people to fess up some good recipes also.
