On a 3 day vacation, I drove from Calgary through Cranbrook, Osoyooos, along the Crowsnest Highway (#3), with my mother who wanted to spend time with her son and see some mountains. We stopped at a number of wonderful stores and interesting spots along the way.
For the scientifically inclined, I highly recommend the Newton Observatory Bed and Breakfast in Osoyoos. The owners have four telescopes for viewing the stars at night and in the day, and are quite knowledgeable in astronomy.
A short video of our adventure along the way was made. Enjoy.
