I may be older than most of you...in order from when I was a kid:
Old Yankee Stadium
Connie Mack (a real dump)
Old Memorial Stadium (in Baltimore I actually like it more than Camden Yards)
RFK Stadium (but for DC United)
The Vet in Philly
Dodger Stadium (one of the best)
Kauffman Stadium (probably the best)
Atlanta Fulton County Stadium
Comiskey (the new one now called US Cellular--probably the worst)
Citizen Bank (I think thats the name of newest Philly stadium)
Minor League games in Frederick MD, Chattanooga, Greensboro NC, Prince William VA, Hagerstown and a few others I forget now.
A few spring training games in FLA (Port St. Lucie, West Palm and Vero Beach--the best place to watch a game.)
How could I forget--The Dome...actually two domes...Skydome in Toronto and HHH Metrodome.
Also Bowie MD for minor leagues.
Doesn't feel like that should be it, but I think it is...
How can everyone forget beautiful Tropicana Field which makes our Dome look like Target Field. The Stingray petting pond behind Centerfield is second to none.
I have been to Wrigley, Comiskey, Jacobs Field, the Dome, and of course Target Field.
I wish we had a better name for Target Field. Like Puckett Park or something. I get sick of all of the corporate names all the time. BaseKetball was right on the money.
