I also have a brick from Memorial Stadium. Fun story behind it, my Grandpa is the all-time biggest Gopher fan I know. From hitch hiking as a youth to Memorial Stadium, long time season ticket holder, and now at the age of 90 watches every game. About ten years ago we were sitting around at his house and he was talking about how he worked hard his whole life but doesn't have a big inheritance. We of course said, that is fine, we don't want any of your money, you spend it as it is yours.
My dad made the comment to him that there was a ring that my Grandpa always wore that he wanted some day. Grandpa looked at me and said what do you want? I said my favorite memories of a kid was when you would take me to the Metrodome to watch the Gophers and someday I would like your brick from Memorial Stadium because I knew how much the Gophers and that stadium met to you. He got out of his chair, went to his bedroom and got the ring for my dad and walked to his shelf and grabbed the brick and said "I want to see you guys enjoy this." It means more to me than he will ever know.
