Not sure how you call it an open house when there's no house there, but Sound Transit will be hosting such an event tonight for the UW light rail station (or for the 90% design thereof). It'll be at the Museum of History and Industry, not far from where the actual station will be. Says Sound Transit:
Sound Transit is hosting an open house for the community to learn about the latest progress on the project and provide feedback on the station design and other issues. Technical staff will be on hand to answer your questions. A presentation will begin at 6 p.m.
