Alton Brown in Cincinnati
He gave a short presentation about where he tought the combination of TV and the internet would take home cooking (he was at the local cable provider's booth). Incidentlaly, his presentaiton was on a Mac (he's a long-time Mac user). It was actaully rather interesting.
He then had a Q&A, which was a bit frustrating for me. One person complained about the "exotic" ingredient in gumbo, file. Though it is not something I expect everyone to have heard of, I got my container, Louisiana's own Tony Chachere's brand, at Biggs (which is all over the city).
He signed autographs, though I choose not to stand in line (I met him before, and he signed my copy of I'm Just Here for the Food). All in all, though, a good afternoon.
