Dave takes a virtual field trip to one of his childhood haunts -- the Griffith Observatory perched above the Los Angeles Basin in Griffith Park. Our tour guide is the longtime Director, Dr. Edwin C. Krupp. Ed's passion for astronomy education and the venerable observatory, built in 1935 and extensively renovated in the early 2000s, comes through as he takes Dave on a trip through time and space at one of California's most iconic venues.
