The Castleton Blue Line Club was formed in 2005 to promote and support the Castleton State College men's and women's ice hockey teams. A non-profit organization, the Blue Line Club is sanctioned by, but not affiliated with the college. All proceeds from season pass, merchandise sales and other fund raisers are given to the department of athletics.

Being a member of the Blue Line Club entitles you to great merchandise, season passes to men's and women's games, e-mail game summaries of both home and away contests, and reception lunches with players and coaches.
