Heading to Montana this weekend, and depending on my motivation, I'd like to go to Fernie, Cranbrook and Nelson, B.C. I would probably enter B.C. in Roosville. Dumb question, I'm sure... What's the best way to exchange money in and out of Canada? I have no idea how much I'll need to wander around for a couple of days. Good campground suggestions near eating/drinking establishments would be much appreciated! Thanks!
