Again, thanks to all for the input....All riders (even my 16 year old son) are experienced, have done extended overnight loops in Gaspe, Lac St. Jean, etc....just never in this area....We are all riding "Fresh" Ski Doo 800's so hopefully all will go smoothly. My biggest issue at the moment is just have a clear understanding as to where to fuel up between St. Z and Clova...between Clova and Val D'Or and between Val D'or and Mount Laurier. Any further input on this would be most appreciated! All my best and many thanks to everyone that has weighed in on this post!!! Very helpful!
