The Fremont Troll
The Fremont troll took up residence under the north end of the Aurora bridge on Halloween 1990, and hasn't left since. He was sculpted by four Seattle area artists -- Steve Badanes, Will Martin, Donna Walter and Ross Whitehead -- for the Fremont Arts Council. The head-and-shoulders sculpture is 18 feet tall.
The shaggy haired troll glares southward with his shiny metal eye -- a hubcap? In his left hand, he crushes an old style Volkswagen Beetle, which originally contained a time capsule of Elvis memorabilia; it was removed after the car was vandalized and the California license plate was stolen (The crushed car and out-of-state plate were meant as protests against "outsider" development). There are plenty of places to pose, and interaction with the troll is encouraged.
The community pays tribute to the troll every October 31st with a mobile "Trollaween" party, starting under the bridge and wandering to other funky art sites and events in Fremont. Of which there are plenty: Fremont is also home to the Largest Lenin statue in the US.
The troll achieved more notoriety in 1998 when the a man shot a bus driver and ran the bus off the Aurora bridge, crashing on top of an apartment building. The building is adjacent to the troll, and was reported to get as much attention -- for a while you could still see evidence of the impact.
