Great American Ballpark - Cincinatti, Ohio
America's Greatest Past-time
Ken Griffey Jr.
Since I was a kid, I've had a deep respect and fascination for the game of baseball.  It has consumed, even now at the tender age of 27, more than half of my life having started at 5 years old, until I was 19 - playing year-round every year until an injury forced me out of the game.  But, my travels over the past few years have allowed me to visit some great ballparks around the country, and to finally watch my favorite player perform - Ken Griffey Jr.
