Johnny Wowk of Peabody, also known as "Johnny the Walker", was celebrated at the North Shore Mall after reaching the 20,000 mile mark. He's been walking daily for years. Here, Mark Whiting, general manager of the North Shore Mall and Susan Ford of Lahey Clinic, which sponsers the walking program at the mall, give several gifts to Wowk including a new pair of walking sneakers and a backpack.
