Read the passage. The San Francisco Bay is famous for many things--the Golden Gate Bridge, Alcatraz Island, where the old prison is now a tourist attraction,
and "junk sculptures" on the street of the east shore of the bay.
Driving along the Eastshore Freeway near Berkeley and Oakland, you can see these huge folk art structures built of driftwood and plastic
and hubcaps-anything people find washed ashore or discarded. A castle with flags flying a dinosaur big enough for kids to climb on, horses and
riders, immense weird bug-there is no telling what will be there. Since the early 1960s, hundreds of people of all ages have built things there.
squishing around in the mud with hammers and nails. They use what they can find for supports or sides, heads or hats, flags or flippers.
A sculpture may stand for a few days, a few weeks, or longer. Winds, rain, and tides can change a sculpture. A piece blown off one can be
used on another. Like people who make sand castles at the beach, the builders expect their work to be changed by weather or by other people.
That's part of the fun, part of what makes junk art a creative community project. And freeway travelers have something great to look at when
they're stuck in an Eastshore traffic jam!
Why do Eastshore sculptures keep changing?
1. The junk sculpture rules say the forms have to change every two weeks or be taken clear down.
O 2. The weather and other people change the forms after they are built.
03. The tide comes in every night and washes the forms away.
04. The forms are not well built and they fall down when the wind blows.
