Having worked in the James Bay Hydro projects area in the late '80s and having driven it most of the 10 or so trips, I could only hope to do it on a motorbike!
This trip took me from Ottawa to Val d'Or, then near Chapais, a shortcut to Matagami, the strait up to Radisson which is 10k from LG2 Hydro Dam.
There is one gas-food-rest stop at 387km north of Matagami, that's it.
Then from Radisson to Elliot Lake (in one day!) A change of tire in Val'Or total for the day 1640km!
On to Kapuskasing via the scenic Lac Superior / Wawa route.
From there a stop in Val d'Or to say hi (again) to mom & dad and home to Gatineau...5045km on the counter gone 10 days, 6 on the road!
When can I do it again???
