For two weekends each fall, Larimer Square is transformed into a Rocky Mountain Theresienwiese, the official site of Munich's Oktoberfest. Highlights of the celebration include Corporate Night Games, where teams from local businesses compete in the Keg Roll, Pretzel Toss, Polka-thon, and Human Foosball. Plenty of German music and dance are presented and are highlighted by a rollicking good concert involving more than 100 accordion players. The Karneval has rides and midway games and loads of traditional food and beer. There's no general admission charge, but you'll need tickets: beer and food are about 5-9 tickets each, and Karneval attractions are about 3-6 tickets each.
