there's a couple different ways to look at it,....how much is it worth it to you to market your calls,....there is no better place to go if you want to "show" your stuff than in front of 40 thousand turkey nuts,...I never put much "value" on the actual money across the table at the shows, although Nashville always paid for itself and than some. But acutally putting your calls in the hunters hands and meeting them face to face, is hard to put a price on that. It may take a few years and alot of shows, but it's the best way to start your customer list,..you will sell more calls to people who weren't at the show, but saw one of your calls that their buddy bought. Custom calls need to be seen in person, touch, feel and most of all listened too. It's hard to do that in an advertisement in a magazine,...and more than likely they aren't going to come to your shop and ask for the calls right now.....you gotta go to them.,...show your stuff,...make an investment.... But don't have the "get rich quick" thinking. Be patient with it, and enjoy the craft.
