Boston has the Duck Tours,or DUKW tours, which are tours that take place on purpose-built amphibious tour buses or military surplus DUKWs and LARC-Vs. DUKWs operated by Boston Duck Tours have been used at least five times since 2004 for "rolling rallies" to celebrate sports championships by New England-based local pro sports teams.[5] The Boston Celtics celebrated their 2008 championship, the New England Patriots celebrated their championships and the Boston Red Sox celebrated their 2004, 2007, and 2013 World Series victories with a parade of 17 DUKWs carrying members of the team over land and across the Charles River. The Boston Bruins also celebrated their 2011 Stanley Cup title with a duck boat parade.
