For folks planning a trip out, here's some links I've found:
Convention and Visitors Bureau http://www.birminghamal.org/index.asp
(They don't have the game listed on their events calendar yet - maybe if
enough people hit the site and request a brochure, mentioning the game,
they'll add it?)
The Travellers Guide to American Soccer doesn't have a guide to
Birmingham, unfortunately
Birminham Airport http://www.bhamintlairport.com/
(currently served by American, Continental, Delta, Northwest, Southwest,
United, and USAir)
