There were a noticeable number, confirmed by speaking to them, of Packer fans that made the trip up from the states. They had a great time, judging by the cheering, screaming, laughter and liquor they were consuming. The wave that carried on for twenty or so cycles around the stadium got most fans breaking into ovations, foolery, and lots of commotion. NFL has a lot of fans.
It was somewhat shocking to witness the difference in the foot print of a NFL field overlay a CFL field, first hand, and absolutely further convinced me the bigger field adds more chance for exciting plays.
A Bomber game is better value for the money but being there was a cool experience.
