Someone asked me about synchronized skating events in the US so I looked up the current schedule:
Eastern Sectionals Jan 29-31, 2004 in Providence, Rhode Island
Midwestern Sectionals Jan 28-31, 2004 in Geneva, Illinois
Pacific Sectionals Jan 29-31, 2004 in Salt Lake City, Utah
US Nationals March 2-7, 2004 in San Diego, California
World Synchronized Skating Championships April 1-4, 2004 in Zagreb, Croatia
It's a very active sport around the world, but doesn't get much publicity (like roller figure skating, which Tara Lipinski did successfully for a while before concentrating on ice skating).
For more information about clubs around the world see the list compiled by Sandra Loosemore at her website:
