The game of Let's Say, this week on WireTap. Let's say you could bring about world peace with a snap of your fingers, but, if you did, the sun would never shine again. What would you do? WireTap imagines what may be and what might have been. That's WireTap, with Jonathan Goldstein, Sunday afternoon at 1:00 (1:30 NT, 4: PT) on CBC Radio One.
