I went once (2006-2007?) It was pretty big.
Almost every snowboard company has a vendor booth set up, with all their new gear for sale (boards/bindings/boots/outerwear/etc).
Almost every resort in Western Canada (and a few from Eastern Canada & the US) had a booth set up to promote their resort. There was also a rail contest going on.
All with free stickers
You should have no problem finding your red pants and white jacket there.
Does never summer usually have a booth here? wanting to get a deal on a revovler
Not sure, but if I had to guess I would say that's very unlikely. Just email them (NS) and ask though, and ask where they have retailers in your area. Rude Boys in Banff is one. There is a thread called "never summer in canada" (or something like that, check it out)
