Slow Roll is a weekly group bicycle ride in Detroit that rallies thousands of people to experience the rebirth of the city at the street level. Join Slow Roll cofounder Jason Hall as he talks about how he’s created a movement, how iPad and apps give him freedom to work on the fly, and how you can start your own Slow Roll. Moderated by Elly Fishman of "Chicago Magazine" at the Apple Store, North Michigan Avenue in Chicago.
