I saw there was the type of sporting goods store in Billings (and Helena) that focuses on the hiking/backpacking/climbing segment rather than the usual ball sports, hunting or fishing. The Base Camp. I went to see what they had. On clearance, maybe.
There were no shoes, apparel or gear that struck my fancy, but... Ooooooo, maps!
free, interactive online versions of these Forest Service maps, but I don’t always have access to the web—particularly in the mountains.
