What is the best route to visit every MLB Stadium?

I'm planning a trip for the 2012 MLB Season, to visit every MLB Stadium (it's been my lifelong dream) by automobile. I am willing to start at any ballpark, and although I've been to Citi Field and Rogers Centre before, I don't mind going again. I was thinking starting in Miami, going to Tampa, then Atlanta, Then DC and Baltimore, Philadelphia, Citi Field, Yankees Stadium, Fenway, then go to Rogers Centre, then around to Comerica and so on. Does this sound like a good plan?
