On my recent visit to Illinois, I filmed a Barnes & Noble Meet the Writers segment. I had already done three radio interviews that day, two from a phone and one at an NPR station. I didn't know the B&N interview was going to be filmed until I was already on my way to the studio.
That was probably for the best, though. I would've obsessed over it if I knew about it too far in advance. (Although, I probably would've shaved, too.) But the host was great, which made the interview fun.
