A bit more on bus ads

My attention has been called to this opinion piece in the Boston Globe from earlier this year, quoting our own John Hennessey:

The National Association of State Directors of Pupil Transportation Services denounced bus ads in 2011 for safety reasons. “Advertising, if it’s effective, draws attention to the ads” and away from disembarking children, John Hennessey, Worcester’s transportation director and past president of the Massachusetts Association of Pupil Transportation, told me.
