Tonight, the Twin Cities will stay up until the break of dawn. All-night party Northern Spark features a variety of happenings, including special performances, hands-on activities, art installations, and more. Hop on your bike, or the MetroTransit, and see the sights of our cities. This year’s theme explores climate change. Things kick off at the U.S. Bank Stadium with a statement from Mayor Betsy Hodges, poetry, and live music. Other places worth checking out include the Coffman Memorial Union, where large, illuminated animals will parade through the air via a pulley system; the Weisman Art Museum, where guests can enjoy electrical sonatas made on the fly; and the Commons, where the Night Library will encourage folks to solve puzzles and other brain twisters.
