The cavernous main gallery at Western Bridge makes possible some of the most impressive shows in Seattle. Back in February, for instance, Euan Macdonald constructed an entire fake mountain peak, two stories tall and adorned with goats and snow. It was one of the weirdest, most memorable exhibits of the year, in a 10,000-square-foot space established six years ago by collectors Bill and Ruth True. (Eric Fredericksen curates the galleries, which include a working kitchen upstairs.) Not every show in the converted '50s warehouse is as successful as the Macdonald exhibit, but no other gallery in Seattle?or museum, for that matter?can accommodate such grand installations. See them while you can: The space will close in April 2012. ?Brian Miller 3412 Fourth Ave. S., 838-7444, westernbridge.org
