If you want distances and driving times, go to mapquest and type in the following addresses:
892 6th Avenue
Fernie, BC VOB 1M0
1919 Columbia Ave
Rossland, B.C. VOG 1Y0
I had an address in Golden, B.C. that worked, but I've misplaced it--no snow up there, from what I hear, which is probably not true any longer. So go the the tourism website for Golden, pick out a street address and input it. Incidentally, mapquest is very cranky about Canadian postal codes, or maybe I'm bad an inputting them.
I tried to get a guy at Silver Star to give me a read on the road from Kelowna to Rossland, but he professed ignorance. But winter driving conditions are definitely a factor to consider.
