I'm heading to France to watch the tour, specifically the Alps stages 8 and 9. There will be a few of us going and we're trying to figure out the best way to swing it. We are thinking of renting a car and camping. How hard is it to find a place on the route to pitch a tent? Stage 8 is Sunday, July 11 so should we be try to get to the stage on Saturday morning? Any tips on successful TdF stage viewing would be appreciated.
