This modern country maintains its traditions and hearty spirit, celebrating many festivals. Its most popular Midsummer's Day finds many Finns lighting bonfires and drinking enthusiastically at their country homes. Finland is also home to the world's longest-running rock festival, Ruisrock. The best-known event is the Savolinna Opera Festival, while the strangest is probably the annual wife-carrying championship, where the winner is awarded his wife's weight in beer.
