"It is illegal to advertise on the outside of school buses in Michigan. Any ads must be placed inside," says this article from the self-styled industry bible.
Ah, the inside, that makes perfect (non)sense. The cost of education, whether it’s public or private, is rising.

Several school districts in Michigan are in talks to establish a co-op to let national advertisers get access to those impressionable minds.
