Hi,
We emigrated from the UK to Alberta last October. We settled in the town of Okotoks, just south of Calgary. Some 10 months in, it's feeling like a good decision. A nice town, good community feel, easy access to the Rockies with the most fantastic scenery and wildlife, easy to get around, etc. We're very happy. We keep a blog of our life out here as we experience it. Feel free to take a look - might give you a better feel for southern Alberta as a possible location.
