Even on race day, the most crowded of the annual events held here (there are also NASCAR and Motorcycle races), you can move pretty freely around the place, which has a county fair-like ambiance, with plenty of food, merchandise and booze stands and trailers everywhere you turn.
Hotels and tourism also get a boost as more international flights arrive, given that certain flyaway events (the racesheld outside Europe) sell at least 50 percent of their tickets to foreigners.
