The initial email announcing parking mentioned “continuing the model used at Garth and Winter Classic.” I believe tailgating was permitted at those events. We are going for it.
(Stars vs. an opponent TBD). I assume they aren't counting on it being as chilly as last weekend. The average high in Dallas on January 1 is 56 degrees (although I don't recall it being that warm for any of ND's 7 outdoor Cotton Bowls).
There also was an outdoor game at Dodger Stadium in January 2014. Temperature was 63 degrees at faceoff, but the ice was just fine. The game was at night, so there was no glare issue.
