Mike Johnston is the mayor of Denver. I like Mike though we probably only agree about half the time. I've been looking forward to this conversation and hope you find it informative. 

Tom Mullaney is professor of history and of East Asian languages at Stanford, and he has one of the most awesomely nerdy areas of interest and research that I've seen in a long time: Chinese typewriters and early Chinese computers (not necessarily electronic)

And... hot dogs.
