Hey man,
There are some people that hit alta and a couple of the lakes around the whist....you can also head out back piccolo flute area on a good day...with good conditions (i.e solid snow conditions). As for dealers in the couve i think pacific boarder might have some stuff.... Me and a buddy where actually thinking of starting our on store ... but that won't help you now..... talk to dan sheridan at
http://www.kitesurfcanada.com and he can hook you up with some gear at a good price.
Cheers,
Shwern
