During the second week of June each year, race car aficionados converge on Le Mans (population 147,687) to watch this careening, 24-hour endurance race. Corvettes, Porsches, Ferraris and myriad other souped-up speedsters whip around the 13.629km Circuit de la Sarthe track at the world's oldest sports-car race (www.lemans.org), first run in 1923. The rest of the year, visit the museum, which houses over 150 vehicles from an 1885 De Dion Bouton et Trepardoux steam-driven dog cart to past winners that are just a bit speedier.
