road trip anyone?

I'm thinking about driving around the country next summer, visiting the 23 Major League Baseball stadiums I have yet to see. I think it can be done in about 40 days, though I'm still working on the optimal route between the 20 cities, and can't really plan in earnest until the 2007 schedule comes out.

It's an entertaining math problem, one I would be better equipped to solve if I hadn't dropped combinatorial math.
