I'm new to turkey hunting. I only went once with my husband, but I want to go again with him. I was thinking of buying him a turkey call, and I've seen the box calls on TNN, but I don't know if these are the best ones to use. Are some calls better for different parts of the country, or do you buy calls for different times of the year. I just don't know enough about these things to buy one.<P>Help.
