As promised, below are my personal rankings of the baseball stadiums that I’ve visited. Combining my love for baseball, travel, and architecture, I have either attended a game at or taken a tour of 26 out of 30 stadiums. I have also created albums with pictures from each of the ballparks.

Both the rankings list and the facebook album will be updated as I visit new stadiums.
For more stadium information check out www.ballparksofbaseball.com. This is a really cool website that I recommend you view as well. There’s also a facebook application called “Stadium Tour” with pictures of all stadiums, not just baseball stadiums. It’s pretty cool because you can give each stadium a 1-through-10 ranking and leave comments.
Thank you so much for this list! All my loves as well. Don’t forget to check out Camden Yards where the Baltimore Orioles play-what a magnificent old house. But as long as you have my team, the Brew Crew, on there, you are A-OK. Actually, for any latent Yankee fans checking out this list on Facebook, you should download the Life Changing Box application. Its a fun little prize game where you can win a trip to NYC to watch the Yankees this summer. I’m doing PR for the company and the other prizes are pretty rad too. Thanks for this list and keep on travelling!
