This is amazing! There is a mile long boardwalk at Nisqually Refuge that goes over the Estuary. Last week was my first time walking on it. I should have checked this place out years ago. I went during high tide, so there was water under most of the board walk. I guess when the tide goes out, it’s all mud flats underneath. I am curious about the different birds that come by with the changing tide… So expect many more photos in coming months!
