November 24, 2009 (CHICAGO) --Former Vice President Al Gore came to Chicago Tuesday to sign copies of his new book "Our choice."There was a long line of supporters at the Borders book store on State Street. "Our Choice" is a follow up to Gore's Academy award-winning documentary "An Inconvenient Truth."
Gore has championed environmental issues for many years.
His book is said to be a call to action that answers many of the questions posed by the film.
