We went to see this free public performance at Gasworks park. They have live music, dancing and some singing, otherwise it is silent. They had several lighted decorated boats and things on the water. You can see a lit bed on the lake in this photo. There was also a giant swan and several babies that came by later. They also had lights on balloons and sent them out into the water. you can sort of see that in the photo- the purple-ish glowing lights on the water. It was super neat and reminded me of fireflies as they danced above the water. The girls and Tim loved the show. Maybe there will be one next time you visit seattle.
