BONSPIEL
Bonspiel
A Bonspiel is a curling tournament, consisting of several games, often held on a weekend. Historically prior to the twentieth century many were held outdoors on a frozen freshwater loch. Though not mandatory, curling teams involved in bonspiels often wear theme costumes. Today almost all bonspiels are held indoors on specially prepared artificial ice.The above text is a snippet from Wikipedia: Bonspiel
