On today's show: saving fish from hungry gulls and freezing temperatures. We hear about the annual race to get fish out of Alberta's irrigation canals; Calgary has some pretty spectacular parks, and one local artist set out to capture their beauty using brushstrokes in a new book; it's been ten years since Christopher Nolan released the sci-fi drama, Interstellar, and there's a chance to catch its otherworldly score live by the original organist himself in Calgary tonight.
