Just thought I note this regional show, annually, in MAdison WI. A lot of manufacturers and service providers (parks and outfitters and such) of canoe, kayak, SUP, and all sorts of gear PLUS several teardrop and other trailer manufacturers exhibiting, notably TC Teardrops and Chesapeake Light Craft. And some good presentations - like 10 every 1 1/2 hours from Friday afternoon to Sunday afternoon. Aluminum chef competition always a treat.
I've never seen a session on teardrops - maybe someone here who likes to present should consider proposing that to Rutabaga, the store that organizes the show.
And if you do go, I'd enjoy meeting up - I'll be there for all three days.
