Hmmm...
For Gamecock stuff.....
Watching Big George run over everyone's face for the 79 & 80 seasons. I showed up on campus and had no idea of who he was...attending the GA/SC Herschel/Big George battle at Athens form the scaffolding on the train tracks.
The 2010 Alabama Win and the GA 2012 win were tops...
The 2010 World Series in Omaha...a must trip for true baseball fans.
For other stuff...
Watching mad Max Scherzer's 20 strikeout game from 20 rows behind the Nationals dugout - one of 5 ever in the Major Leagues.
Following Tiger for several days at the 97' Masters. He won by 12 frickin' strokes.
Darlington 1980...where I fell in love with some guy named Ironhead who drove the baby blue and yellow #2 car...Wrangler if I remember correctly
Mets/Yankees 2000 subway series...the game where Clemens threw the bat at Piazza. Have always hated the Yankees and always will.
Redskins 91' Super Bowl win over Jim Kelly and Buffalo. (Made it to the playoff wins over Atlanta and Detroit as well) Sadly some ass named Danny Snyder bought the franchise and ruined it...no longer a fan.
NBA Playoffs - 1977/78 season.. snuck down to the floor and under the basket - security wasn't what it is today - and watched the Washington Bullets out away the 76'ers to win the Conference championship. Dr J, Darryl Dawkins, some guy named Mike Dunleavy etc versus Elvin Hayes, Wes Unseld and crew. I had no idea how big them boys are until I got close up.....
Have a bunch more but figured this was a good list......
