My son (A FIRST alumni at Ga Tech) is currently studying in Spain. You can check out his online journal at
www.Xanga.com/silentdan (he started out keeping it pretty up to date but not lately) and e-mail him for more info.
Basically at Ga Tech, it's cheaper to study abroad than in Atlanta if you're from out of state because they charge you in-state tuition for that semester. He saved up his humanities and electives for this semester - they also have other programs in England and France where you can take engineering courses.
