David talks to cartoonist Josh Shalek, author of Falling Rock National Park, about learning his craft through the works of Bill Watterson, Bill Amend, and Gary Larson, how growing up in the southwest became his setting for Falling Rock, and how transitioning from a daily strip helped free him up to the possibility of larger stories.  Plus, David checks in with Northampton filmmaker Ali Kasemkhani to talk about his upcoming premiere of his new film "Number Two."
