There is a map on the CLUBS page
where you can find all the 3-Wall and 4-wall courts in Fort Collins, Boulder, Colorado Springs, Glenwood Springs, and the Denver metro area, including Aurora, Arvada, Littleton, Lakewood, Englewood, Greenwood, and Centennial. Shuttles offer new players and veterans alike the opportunity to just show up and play in competitive games without having to pre-arrange a game with 1 or more other players. Rules on how players rotate between courts, partners, etc. are set by the organizer or the club and generally involve timed games (10 to 15 minutes) and alternate scoring rules such as scoring on every side-out regardless of who served, and so on.
