The Chelsea Jewish Foundation will hold its fifth annual ALS & MS Walk for Living on Sunday starting at 10 a.m at the foundation’s Leonard Florence Center for Living, 201 Captains Row on Admirals Hill. The 2-mile walk benefits the various facilities and programs of the nonprofit foundation, which owns and operates nursing care and assisted living facilities in Chelsea. The Leonard Florence Center for Living, one of its properties, was the first urban “Green House” skilled nursing residence for people with amyotrophic lateral sclerosis (ALS) — also known as Lou Gehrig’s Disease — and multiple sclerosis to open in the United States. Participants in Sunday’s event can walk as individuals or as teams. This year’s event has two new features: an antique car show and a “Friends and Family Day” celebration, both at the Florence Center. WCVB-TV anchor Susan Wornick is the honorary chairwoman.
