I also attended (and still have the ticket stub to) the first (Mariner) game where father and son (Ken Griffey Jr. and Sr.) played in the same game game...in the Kingdome against Kansas City and Bo Jackson.
Love that we’re staying with Seattle sports...LOL, I still have the ticket stub for the first Randy Johnson no-hitter against Detroit in June of 90, I was so hoarse the next day :-)
