For all you Washingtonians if your travelling this summer banks lake/ grand coolie dam is a great place to stop by. Im not sure on the exact days but i think its on friday and saturdays they have a huge laser show on the surface of the Dam. They open the floodgates(?) at the top and a huge wall of water runs down the front of the dam and they shoot the lasers into the water and tell the story of how the valley was made and history of the area. Its a great outing to take your family on.
