These colorful ads from Belgian agency Duval Guillaume, starring penguins and fireflies, respectively, are a darling illustration of the social benefits of mass transit. Of course, buses would never be able to reach either locale featured in the ads. And whether penguins would be allowed on buses at all is debatable. But I get the point anyway. And I'll certainly keep the Hampden Shuttle in mind if I ever see a killer whale tearing down Roland Avenue here in Baltimore.
