Train Q&A w/ Carmen

I convinced Carmen to join me on the train for this road trip. And since we had nothing better to do, I asked for questions on Twitter and Slack and Carmen and I spent some time in the observation car answering those questions. 

We're interrupted by the conductor on the PA about ten times, but in between those announcements, we got to most of the questions. Sorry about the audio quality but... we're on a train.
