American football rules
Super Bowl LI was the first Super Bowl to go into overtime with a 28-all tie between the Atlanta Falcons and New England Patriots, which the Patriots eventually won with James White scoring a touchdown on the Patriots' first drive.
Boston Duck Tours
In 2002, the Boston Duck Tour Ducks were first used as the parade vehicles for the New England Patriots after the Patriots won Super Bowl XXXVI over the St. Louis Rams. Since that time, the Boston Duck Tour Ducks have participated in eleven professional sports championship parades in Boston. There have been five for New England Patriots (2002, 2004, 2005, 2015, 2017), four for the Boston Red Sox (2004, 2007, 2013, 2018), one for the Boston Celtics (2008), and one for the Boston Bruins (2011). The Duck Boats were first planned to be used for the New England Patriots in 1997 however they did not win Super Bowl XXXI. While much of the parade routes over the years consisted of the DUKWs staying on land, some featured the DUKWs traversing both the land and across the Charles River.
