Magic Wheels is a black motorcycle club founded in 1974 in South Los Angeles by five young men who started riding motorcycles because gas was too expensive. The Seattle chapter, based in Georgetown, was founded in 1977. For one day only, it's opening its clubhouse as a fundraiser for Hot Grits, a new rock musical about four black women who form a punk band. Hot Grits will play, along with some other bands. Wieners and grits will be served. Go. (Magic Wheels Clubhouse, 5901 Airport Way S, 3–7:30 pm, $10 at the door, 21+.)
