Red Bull — known for hosting relatively creative and dangerous events like their Flugtag, where people build their own flying machines and participate in a competition involving flinging themselves off of tall things — has been bringing the joys of soapbox derby-ing to Mount Adams for several years. The competition consists of both design and creativity judging panels for the derby contestants’ vehicles and a daring timed race through Eden Park, routinely loaded with epic crashes and glorious triumphs from the charmingly unique homemade vehicles, built from materials ranging from cardboard to steel.
11 a.m. Saturday. Free. Eden Park, 950 Eden Park Drive, Mount Adams, redbullsoapboxrace.com.
