Scott Gediman is a ranger and spokesman for Yosemite National Park. We got the chance to speak with him during our spring membership drive, and it was so good we recut it for a proper airing! We also close the episode with a conversation with Azeen Ghorayshi, a science writer who is now working for the news arm of Internet Media behemoth BuzzFeed. She tells us about the power of science journalism and why she turned away from working in a laboratory.
