I've been to Morgantown twice, 2005 and 2007 Both times involved some uncomfortable interactions with their fans. Young, old, male, female. Batteries, pennies, and ice balls have been thrown at my groups. During the 2005 trip an 80 year old lady looked at my friend, put her finger in his face and said "I don't like Louisville, and I don't like you", then slapped him strongly across his face. That same trip a monster of a mountain man approached another guy in our group and straight up challenged him to a fight outside the restrooms. It took all of us to convince the guy we would gang up on him to get him to leave. After the epic 3 OT loss we were surprised how ugly and nasty people were. We were again physically threatened had to pick up our pace to exit the area. During the 2007 visit my group was physically threated for going to the will call window to pick up our game tickets. That particular trip melting snow was on the ground and had refroze into ice. They threw ice chunks at my group outside and inside the stadium. After that game we decided to go to a local WVY themed pub called Davey Crockett's We sat down at the bar and immdeiately were surronded by 10 guys. One of them tapped me on my shoulder and told me "You have alot of nerve coming in here. Visiting fans don't come in here. But since you were brave enough your dinner and drinks are us." That was a weird situation, but they literally bought everything we could eat or drink and ended up having a pretty good time.
With all that said I still thought the rivalry was great. For the good of the ACC and getting to play another school you love to hate, I say bring the Eers in. If ND wants to stay independent, grab Cincinnati at the same time and suddenly UofL has old rivals back that surpass any rivalry we have going with other ACC schools.
