Rockinrog this is a trip I want to do also. I think Sept.would be the best time because of tourists/traffic being low.How were the temp.for riding @ different elavations that time of year? I have been across Canada in 1986 on my first BMW 1981 R100RT down the west coast to LosAngeles then east through AZ / CO / back to Toronto. I am from Nova Scotia, Canada.Have you been there yet? I highly recommend the east coast of Canada including Nfld.
