A random discussion of baseball stadiums (OK, stadia) we've been to, came up recently among my baseball fantasy league buddies, and I suggested we list the ones we've been to that don't exist anymore, and when I gave the list, the only response was from one of the younger members telling me I was showing my age. 

Anyway, here it is:

Candlestick Park

Kingdome (Seattle)

Baltimore Memorial Stadium

The Vet (Philly!)

Connie Mack (Also Philly)

Shea Stadium

Comisky (Chicago)

Tiger Stadium (Detroit)

Riverfront (Cincinnati)

Three Rivers (PIttsburgh)

District of Columbia (RFK) Stadium

Cleveland Municipal

Milwaukee County Stadium

Exhibition Stadium (Toronto)

and the (Houston) Astrodome

I might as well list current ones too:

Fenway (Boston)

Wrigley (Chicago)

Yankee Stadium

Citizen's Bank Park

Angel Stadium (Anaheim, CA)

Guaranteed Rate Field (Chicago)

Kauffman Stadium (Kansas City)

Camden Yards (Baltimore)

PNC Park (Pittsburgh)

Ring Central (?) (Oakland)

I've also been to hockey games in Philly (3 places, including the Convention Center for the Blazers), Long Island, Manhattan (MSG), Cherry Hill NJ, Meadowlands (NJ), Calgary, Boston, Montreal, Washington, Pittsburgh

Football at Franklin Field, the Vet and Lincoln Financial - all in Philly and the Meadowlands
