Kim Erbach of Rochester hugs her daughter, Jessi, 14, Sunday as they look at a makeshift memorial in front of the closed doors of Mayo's Plummer Building in Rochester. The memorial was frequently visited during the weekend by those paying respects to victims of last week's terrorist acts on the East Coast. The Plummer doors have been closed only rarely since they were installed in 1928, most often to mark the deaths of high-profile clinic staff members.
