How Many Major League Baseball Parks/Cities Have You Been To?

So I just went to the New Yankee Stadium and have been to the new Citi Field and I make it a point to try to go to a stadium when I get to a Major League City.

Here are the ones that I've been to. The names are the names of the park when I attended the game. These include only the parks that I've either seen a game or done a ballpark tour at:

New York (4): Old Yankee, New Yankee, Shea, Citi
Chicago (2): Wrigley Field (by far the best park in the Majors), US Cellular (White Sox)
Baltimore (1): Camden yards (orioles)
Boston (1): Fenway Park (Red Sox)
Seattle (1): Safeco (Mariners--and I took the ballpark tour there!)
Arizona (1): Bank One (Diamondbacks--and it was a no-hitter for Jose Jimenez of the Cardinals and Randy Johnson struck out 14 and LOST!)
Colorado (1): Coors Field (Rockies)
Houston (2): Astrodome (tour only), and Enron Field (!): Astros
Milwaukee (1): Miller Park (Brewers)
San Francisco (1) SBC Park (Giants)
Washington DC (1): RFK Stadium (Nationals)
Montreal (1): Olympic Stadium (Stade Olympique) (Expos)
GRAND TOTAL OF BALLPARKS: 17

Now most of my friends have been to close to this number and one of my friends has been to about 40 over his many years. So I asked a question of my friends:

Has anyone been to all the major league cities (with or without going to the stadium and I'll include Montreal in this for argument's sake)?

Here are the cities I've been to:

Baltimore YES
Boston YES
Chi White Sox YES
Cleveland YES
Detroit YES
Kansas City NO
LA Angels YES
Minnesota NO
NY Yankees YES
Oakland YES
Seattle YES
Tampa Bay YES
Texas NO (arlington)
Toronto YES
Arizona YES
Atlanta YES
Chi Cubs YES
Cincinnati NO
Colorado YES (Denver)
Florida YES (Miami)
Houston YES
LA Dodgers Yes
Milwaukee YES
NY Mets YES
Philadelphia YES
Pittsburgh YES (and I'd have another ballpark if I wasn't rained out of this one)
San Diego NO
San Francisco YES
St. Louis NO
Washington YES
Montreal YES

So I've been to all but 5.

How about you?
