Paul has inspired me to put together an epic ride that will take those who are stupid enough to come along with me this summer from Boise to McCall using dirt roads. I know of a few people who have done it. I am working with them to get their routes and figure this all out. My guess it will take a couple of days and we will have to figure out support. I just wanted to post this to get an idea of who would be interested. It would be MT or cross bike ridding. Once I figure out how to put in the route in a map I will upload it. Lots of fun. This will be done sometime in late July or August.
There is the route I got from Mike Cooley.
