On this 52nd edition of our program, host David Kelly chats with writers David Turpie and David Leighton who have collaborated on a publication that explains the history of the Reid Park Zoo plus the temperatures are starting to come down as Fall hits and it's time to get out and dance through Tucson. Bridget Gee and Aria Levin from Silent Adventures are back to tell you about the schedule for their second season of touring the city through music.
