I'm much farther away (in Ohio), but I don't recall ever seeing anyone from the BWCA side at a sport show here - could be my memory - but none are on the list for this year either.  We get lots of Canadian places -- mostly eastern Ontario, even Quebec -- but we do get Canoe Canada here every other year or so.  During one slow time I picked Jim Clark's brain about Quetico for an hour or so & he was pretty forthcoming about routes, fishing, etc.  Now granted, I'd been a paying customer in the past, so that may have helped.
Just another perspective.

PS: one thing mentioned (lamented) was that their canoeing / park business was down, but that their cabin business (mostly north of Atikokan) was way way up -- so some of this may be the business model.  Why not invest more where you're going to make more money?
