Sharply-drawn "ghost flames" that change color under sunlight adorn two new PT cruisers at the San Ramon Valley Fire District. And fire safety instructors Danielle Bell and Erick Hubbard are using them to teach CC! to some 4,000 students at 25 schools.

The fire district adopted CC! in 2002, the first Northern California fire service to do so, and led the way for other departments.

The flame cars are a natural fit for the fire department's program, which integrates CC! with fire safety, Mr. Hubbard told the Contra Costa Times in November 2005.
