I am unsurprised to find long time friend of Boing Boing, Howard Rheingold is in part responsible for changing this street sign. I pass it all the time.
Via the Marin IJ:
Three Tam Valley pranksters fed up with the tooth-grinding, serenity-shaking, bumper-to-bumper traffic on Highway 1 took matters into their own hands this weekend.
They changed the “Welcome to Tamalpais Valley” sign near the Holiday Inn Express to “Welcome to Traffic Jam Valley” on Friday afternoon, getting approving thumbs-ups and cheers from the host of motorists inching westward past the sign on congested Highway 1.
“We put it up to improve the quality of public information in a reversible and non-destructive way,” said Howard Rheingold, a 68-year-old Tam Valley resident and former editor of the Millennium Whole Earth Catalog.
