Chip and John regularly send each other email. But is that truly the best way to communicate? Have you ever mailed a letter? This week we meet Joshipine Smith, the last working member of the pony express and champion of the US Postal Service. With her trusted horse Maybelline she travels the west, waiting for another to take her place. We also have Audrey Rothgarden. A celebrity gossip columnist, a spy? Maybe both? She gives us all the celebrity dirt, information on the art of spycraft, and maybe most importantly: Which President was seen at a cock fight.   Guest starring: Serina Stone and Sharon Powell
