I went a couple of years ago, very small(smaller than Nashville, maybe a bit bigger or about the same as Chattanooga) and filled with fish boats and jet skis and pontoons. No cruisers (Chattanooga has a couple of cruisers usually)and a few assorted open boats. No vendors. (outside of sunglasses and gutters)
We went to Nashville last week and it was small.
Atlanta is this weekend (today and tomorrow) and I assume that it too will be the same. All the inland shows are downsizing rapidly. While I understand it's the economy stupid, it's a bit disconcerting.
Last year at Atlanta I talked to a guy at the Lowrance booth about the side scan sonar. He was touting all the fishing capabilities and so on. I told him I was a cruiser, not interested in fish, just wanting to see what's down there. He had a bewildered look, stuffed brochures in my hand and walked off. If I ever find another vendor, I'll try again.
