My wife and I attended the Warrensburg, MO Hamfest on July 14. We got there about 11:30 due to family obligations, and we found that most of the people were already packing up to head out.
Associated Radio from Kansas City was in attendance as well as a radio dealer from Talladega, AL. I can't comment on the educational offerings because I got there too late to enjoy any of them. But the Hamfest itself was nicely done.
