I had the honor of meeting Ms. Palmer at Dragon*Con 2005 in Atlanta. She was just a delightful, personable, friendly dear woman, and I have a great memory of meeting her. She played, among many roles, Mrs. Pamela Voorhees in the first two Friday the 13th movies. A note of trivia - It was she who was the killer in the first movie, not her character's son, Jason. If you ever get the chance to meet her, you should definately do so. You'll just adore her.
