But seriously, Sparty is too immature of a fanbase to have them at night - last year they tore up the campus, and damaged personal property. I don't expect it to be any different if they come around for a night game - win or lose, they destroy where they're at.
Ohio fans are loud and violent, and I have similar concerns as I do with MSU. Additionally, the cold weather would make the travel of 115k people dangerous from the stadium afterwards. It's moot anyway though since the B1G bans November night games.
ND would be cool - but I'd like it if it was done every 3/4 years for major, non-con opponents. I know that may limit us to Notre Dame from here on out, but if we have a night game it should be against a competitive program. I'd be ok with it against AFA - except that next year would be too soon. And the first one being a rivalry game against one of the most storied programs in college football - it would fall flat to do it next year against Air Force.
