Re: Most amazing baseball feat.
Live: I was at the game in the 1990's at Riverfront where Mark Whiten hit 4 HRs. Also in 1998 watching Mark McGwire hit batting practice during the Maris chase and catching BP HR balls in the Red seats left and right!
TV: Halladay's no-hitter or the Boston Red Sox amazing 2004 playoff run of comeback wins. David Freese '11 WS performance rates pretty high too.
Attended 1976 World Series in my Mother's Womb. Attended 1990 World Series Game 2 as a 13 year old. Want to take my son to a a World Series Game in Cincinnati in my lifetime.
