A vast, flat wilderness.
Manitoba has fascinated me forever. It's a huge pine wilderness in the middle of North America with one of the continent's coldest cities. In the US, we also hardly ever hear of it. Sounds like plenty of places to explore!
Despite how much it interests me, I've only made it there once. Winnipeg is a decent city, and I thought Riding Mountain National Park was pretty cool, too. I'd love to get up farther north some day, armed with a canoe and plenty of mosquito netting.
