LILY DALE - Last month, Sylvia Lileberg, known as "Syb" - was not feeling well. After checking with doctors, she was surprised to learn she needed heart surgery. Still, another unexpected development was in store. Instead of the one scheduled bypass, there were four completed during surgery on Jan. 9, at the Hamot Hospital, Erie, Pa. These days, Syb is on the mend. She's already able to attend to important tasks like tending her window-sill garden, and Toby the dog.
