The airport was the first place that my feet touched in amerikkA (long back, in the 90's) :-) So, a couple of years back I deliberately stopped in the city (albeit in McD) to spend a few moments during a long-drive :-)
Are you planning to be in the area for another week? I'm planning to drive to Columbus during the long weekend (visit a relative who had a new-born)...may be able to meet you in person, even if it's for a brief while:-)
