Yes, I've lived at those latitudes and I think you're right about Sept road conditions. Plus we should get comfortable riding and camping temps. Still finding a few older RRs about the Route Du Nord and the Trans Taiga Road. Good stuff. Wouldn't be surprised if there's snowmobile traffic between Radisson and Schefferville especially if sledders can trailer their machines to the end of the TT. Probably a nice days run to Schefferville on snowmobile in March or April.
