Fringeopolis is in full swing in Old Strathcona and there’s something a little extra for the kids. A Carnival with rides and games. But this is no regular carnival. It’s the world’s first Sustainival. The rides are all powered by a generator that burns vegetable oil. Rod Kurtz continues his summer series on First-Timers with a visit to the Sustainival, and a conversation with it’s creator Joey Hundert.
