Nice, trip, shows there's much more to France than the Alps Shame I hadn't seen your route sights request thread thingy before. Puy de Dome is good, but 10 minutes from there is the notorious Charade Grands Prix circuit. The old, dangerous parts are now public roads and it's pretty awesome to drive down them trying to imagine GP cars racing there in the 60s and 70s. Recommend a quick half hour detour for any motorsports fans in the area.
