The sign has stirred Portlanders to post pictures of people named Bill on the fence, including Bill Nye the Science Guy, Bill Clinton, Billy Crystal, William Shatner and Bilbo Baggins. (There's also a picture of the bill from Schoolhouse Rock.)
Parks and Recreation spokesman Mark Ross says the fence was getting a lot of garage sale posters and band handbills. The golf course added the sign after a neighbor complained.
"It was a very Portland reaction," Ross tells WW.
The most recent picture of the fence, released by Portland Parks & Recreation, shows more than 60 Bills. Parks and Rec posted the picture on its Facebook page today.
Ross says after the collection of Bills started Parks & Recreation and Eastmoreland Golf Course agreed to keep the pictures up.
But which Bill is Ross' favorite Bill?
"Mr. Bill was a great one," Ross says. "He's probably tied with William Shakespeare. But it's like asking someone, 'what's your favorite dessert.'"
