Attending Jackie Robinson's first game breaking the race barrier in professional baseball would be something. 1947.
Being at the Miracle on Ice when our lads beat the Soviets in hockey, that'd be cool. 1980.
Watching Roger Bannister break the 4-minute mile would be a memory for a lifetime. 1954.
Seeing our lads in orange beat Miami in the Sugar Bowl after the 1985 season, earning the historic title "Sugar Vols," I'd love that.
Seeing the Miracle at South Bend, biggest comeback in history against the Fighting Irish on their home turf, would love that, too. 1991.
Any game from any of General Neyland's championship seasons, I would cherish that--just think how much we'd learn about how football felt back then, just being there for one game!
Ditto for any game watching the Lady Vols in any of Pat Summit's championship years.
Those are the events that come to mind first, for me.
Go Vols!
