This is really it. Your last chance to visit the best private contemporary art exhibition hall in Seattle history. After an eight-year run, Western Bridge, the place devoted to the collection of Bill and Ruth True and curated beautifully by Eric Fredericksen, is closing after October 20. The building in itself, by Roy McMakin, is something, with its gigantic parody of a double-hung window and its lovable patchwork wood. The current installation involves hundreds of baseballs. Don’t trip on your tears. (Western Bridge, 3412 Fourth Ave S,, noon–6 pm, free)
