One more suggestion: While driving around SXM the days before the Super Bowl, listen to 91.9 FM. I'm confident that bars will be advertising Super Bowl events on that radio station.
As an aside... While bars and other merchants in the States are required to refer to the Super Bowl as "the big game," or something like that (unless they have a licensing agreement with the NFL), not so on the island! Merchants can get away with using the words "SUPER BOWL" in audio and print advertising! No enforcement!
