Tailgating in the winter is not just cold, it's hardcore.  Many bring grills and fire rings to keep their hands warm while swilling a frosty beer. The best part is, later you get to watch the game in the cozy comfort of the 60 degree dome!  The atmosphere in the dome is loud and electric and worth the hours you put in out in the sub-zero paying hommage to the Minnesota Vikings.  Tickets are always easy to get online, here's a link:  https://oss.ticketmaster.com/html/pack_planlist.htmI?l=EN&team=vikings&selID=152   -  When you get to the dome, be sure to enjoy at least one dome dog with all the fixin's  :-)
