Boston Globe 5/6/13: Law Abider’s Guide to Self-Promotion. IN THE summer of 2007, Wayland resident Mark Peter Hughes packed his family in a shockingly yellow van and drove 13,000 miles across the nation on an extended vacation, flouting an unknown number of laws along the way. The crime was not speeding, but advertising. The car was a billboard in motion, encased in a vinyl “wrap” hawking Hughes’s website and book. While Hughes and his wife look at the 1996 Honda Odyssey and see “family minivan,” local governments look at it and see “commercial vehicle.” It’s a distinction that can prove costly.
