I have kept meticulous records of "major" (professional sports, major college sports) sporting events I have been to. These records include the score, attendance, most valuable player of the game, miscellaneous notes, etc. I have also kept records of how each team has done in front of me, as well as record at each venue. While it would be too much to show all my records, here are my records for each of my favorite teams, as well as some of the most notable and favorite games I have been to.
