Last fall I watched a live chat featuring ancestral health advocate Mark Sisson and creator of the fitness program P90X Tony Horton. At the end of their conversation they held a giveaway for some attendees to receive autographed copies of both authors’ books. I was one of the chosen few. As it turned out Tony Horton, author of The Big Picture, ended up signing both books so I think I may have the only copy of Mark Sisson’s The Primal Kitchen Cookbook signed by Tony Horton. Cool!
