When I was in Minneapolis recently and went to Target Field since the Mets were in town, I was conversing with some Twins fans and they said it's common for Jays fans to come when they are in town, though not quite to the extent of ones going to Seattle. Probably cause Minneapolis is further from the Canadian border than Seattle.
It did get me wondering, since I assume the Twins are the 2nd most popular team in Winnipeg (it is a Vikings town after all), what it must've been like from 1991-1993, when either the Twins or Jays won the World Series all 3 seasons. They even played in the 1991 ALCS, which was the first ever playoff series to be played entirely indoors.
