I just got back from taking my girls for a week to ND. You can stay at St. Edwards hall if you like. They have bikes you can ride and a kids room. I took my girls to the Basilica every evening for prayers. I also took them to the "Rock" to go swimming. I have a nice black and blue mark from trying to splash off the high dive. I weigh a lot more than I used to and got a lot more spring off the board than the last time I was on one.
My girls were in soccer day camp so I would wander around or watch them while they were in camp. I strolled in through a back door of the Joyce center and got to some areas I don't think I was supposed to be in. Ended up in the football dept! Take them to the second floor in there and they can see all the Heisman's and Sears Trophy along with things from all the other sports the University has excelled in. I ran into Charlie Weis no less than 4 times. Met most of the starters just strolling around. It's difficult to get into the Gug but if you hang out at the stadium by the tunnel all the players walk through that gate at some point during the day.
I got to talking with one of the groundskeepers that had been there for 22 years. Really a nice guy. He gave me his name and told me to stop by gate 8 at the stadium and he would give me a tour of the inside, places nobody else gets to see. I think I will take him up on that when I go up for some games.
