That's pretty unlikely. If you wake up and a bear have ventured close to your car, chances are it'll be more scare then you are when it sees you are awake. Unless you put a box full of food just outside your car and my bet is that other animals will get there before any bear (squirrel, deer, groundhog, porcupine, mice, etc.).
Ah, you're lucky! Wish I could join you!:-)
Actually, I have no idea about the James Bay area, but I know for a fact there was a restriction for the TransLabrador Highway with almost all the renatl companies. I believe a part of the James Bay Road is still unpaved, I guess it depend on how far you plan to drive.
My pleasure. It's pretty unusual for people to ask about such remote places. I'm delighted to learn I'm not the only one who's interested in off the beaten path (in both senses) roadtrips.:-)
