These are a Seattle land mark. They were moved several years ago and I recently found where they placed them! There is a big hat to go along with them, but it hasn't been refurbished yet, just the frame work. It was comon in the early 90's to see kids skateboarding in the hat! Here is a link for some of the history and refurbishment on the project, out dated:-(
