I'd say so, at football games. Especially at college football games. There is a college game played every year where i live in Jacksonville, Florida between the UNiversity of Florida and the University of Georgia, it's a neutral site game they have been playing it here just about every year since 1933. The stadium is split 50-50 between both sets of fans and it's basically a weekend long party. They call it "The World's Largest Outdoor Cocktail Party."

Here's what it looks like in the stadium, Georgia fans in red and black on the right and Florida fans in orange and blue on the left.
Sorry to rant there. But it's about the best tailgating experience there is.
