MLS rivalries are among the most anticipated games of the season - from the the Texas Derby, to the California Clásico, and of course the Cascadia Cup. Even the newest rivalry - El Tráfico - has become must-see TV. For supporters of the burgundy and blue, the Rocky Mountain Cup, a 13-year-old competition between the Colorado Rapids and Real Salt Lake sits atop the list of rivalries for fans and players.
The RMC began in 2005 with Real Salt Lake's first season in MLS. Fans from Utah and Colorado rallied together to form a bi-partisan committee of 10 supporters (5 from each club) to outline the competition.
