Every work day I pass by the enormous cement factory and kilns of the Ash Grove Cement Co., just west of Highway 99. You can’t miss the factory and its two enormous kilns. The facility, owned by a Kansas-based firm of the same name, is as much a Seattle landmark in my eyes as the more famous Space Needle. I finally took a bike trip there this weekend and snapped a few pictures. I love the designs of industrial facilities and how function dictates form.
