The great recession killed the National Houseboat Expo in Louisville several years ago and the common opinion is that it will never be back. After that, it turned into "on water" houseboat show at State Dock on Lake Cumberland. We went a couple times, but didn't enjoy it much. There were a few advantages to holding it at a marina, but many disadvantages too. This site says the expo has been cancelled until 2019. I wonder what, if anything, is planned for next year. And where would it be held?

The recession drove several major manufacturers out of business, but the 2018 Buyers Guide made me realize there are several new players not to mention that Gibson is back. The older companies that are still in business have streamlined their operations and seem to be doing very well. We'll just have to wait and see, I guess.
