This is an actual traffic report from the San Francisco Bay Area this morning: There was a report of a "killer tumbleweed" traveling southbound through San Jose on Highway 101 which had flattened a car tire when a vehicle drove over it. It was last reported heading south toward Gilroy. (I don't think that the CHP's SWAT team had caught up with the tumbleweed yet so it still might be a danger to freeway travelers.) Be careful out there.
