What..a turkey hunter keeping a secret , perish the thought. I sell lots of calls to forum members who dont ever post pics of them. One in particular says he feels like a braggard if he posts new calls he has bought. He explains that alot of fine people who visit these sights arent fortunate enough to buy a bunch of custom calls so he prefers not to flaunt what he buys.
If you are ashamed about buying a call from someone who has a less than honorable reputation, then you probably shouldnt have bought it to start with. It seems like you are beating around the bush about a particular situation or callmaker.
Personally the onky thing I ask from a buyer is that they take my call hunting and if it plays a part in a successful hunt, i ask for a picture.
