In 1969, Union Oil's Platform A blew up off Santa Barbara, the most visible and largest human-caused oil disaster up to that time.
Don't we wish that the extent of the current Gulf gusher were so small.
Here, exhibited among other '60s relics, is a preserved specimen of the tar that washed up on southern California beaches:
Within days of the spill Bud Bottoms helped form GOO -- Get Oil Out, an anti-offshore drilling advocacy group. He contributed his pictures to the exhibit.
Fury about the Santa Barbara spill was thought to have contributed to the founding of Earth Day the following spring and continuing Californian hostility to drilling, however fond we are of our cars.
