I am not saying that the OP should expect the runners to stand around and sign everyone’s stuff, but here is a true story… When I was a kid, my grandfather took me to Wrigley Field to see the Cubs play the Cardinals in a regular season day game (Cards won).
After the game, he took me around to the back of the stadium where the players would exit. How he knew this, I have no idea. This was 1987 and I was eight, so a lot of this is a blur. Someone else waiting to see the players told us that Andre Dawson – my favorite player in the world and idol at the time – drove a royal blue Camaro Iroc-Z. When that car came screaming up the exit ramp in the garage, I stuck my hand out with a baseball for him to sign. He slowed the car, took the ball, and signed it. Insane.
It sat in a glass box in my childhood room and then when my parents moved (in my adult years), my mom threw it away. Moms are hilarious.
