Greatest sporting event you ever attended?

September 16, 2007. U.S. Cellular Field Jim Thome 500th homerun!!!!!
It was the bottom of the ninth, 2 outs, and we were just about to leave. We decided to stay to see if just maybe Jim could pull through. And he did! That was only the 5th game all year i went to. I had a choice of 5 games the whole year and i picked the 16th of september!
