Urban foragers are people who eat what grows naturally from a very unnatural place— a city. In this all-vegetarian Sky Full of Bacon podcast, urban foragers show us how they find food all around them. Chef-blogger Art Jackson shows us what's growing around his home in Pilsen, and then foraging expert Nance Klehm, Art and I nibble our way through a remarkable wilderness literally in the shadow of Chicago's skyscrapers.

If you're feeling cabin feverish, this podcast (shot in September and October) will take you back to a sunnier, greener time as we discover the hidden world growing within the concrete jungle. More info at skyfullofbacon.com/blog (17:45)
