The IDBDR is on my short list of rides for next year. Really looking forward to seeing more of the details on this route. Lived out in northern Idaho for a while, never got a chance to make it out in the back country but plan on fixing that mistake. Its a beautiful state lots of public lands and solitude.
My only concern is that 1400 miles will be rough to finish in a week like the other routes, unless there is a good chunk of it that is pretty fast moving. Well that and all my friends that ride are afraid to get their Harley's dirty, so ill have to find someone to ride the route with.
