Yes, first and foremost, thank you for the door prizes!

I only have one small complaint about them...I didn't win one.  So that's my first suggested improvement.  Make me a winner!  :P

I'd agree with the opinions expressed about featuring speakers covering more advanced topics.  I'd definitely go to more seminars if I could find some that didn't cover primarily basic, readily available information.

Ideas: 
Remote and lesser-known picto sites in Quetico
Planning expeditions
Canoeing Major Canadian Rivers (in or out of PP's)
Anything by Marten Kehoe
Ultralight canoe-camping

...and I could keep going

I would also suggest having your speakers rate their presentations as basic, intermediate, or advanced.  It would also be nice if the blurbs about the presentations were less about the presenters themselves and more of a summary of what, specifically, they plan to cover in their presentation.

Finally, I get why you have to charge admission for the event.  The Alliant Center isn't exactly hosting you for free, I'm sure.  I do appreciate the discounts that many of your vendors offer for the show and I find that this more than covers the price of admission if I spend $100 or so...and with my kids getting the canoeing bug, that's likely not going to stop anytime soon.

But as others have said, the main draw for me is the QJ gatherings.  If those came to a halt it's highly unlikely that I'd make the trip from the Twin Cites as the gas/motel expense more than eats up any savings the vendors offer on gear.

Hope you find this thread helpful and I do appreciate your request for feedback!
