Subatlantic Subway

I was waiting for the train the other day and casually glanced at one of the MTA's self-congratulatory posters about how ecologically sound they are. While struggling to believe their claim of recycling 63% of the trash collected at their stations I noticed another little item at the bottom of the page that was (at least to me) much more credulous. Apparently they have been donating old subway cars towards creating new reef habitat along the eastern seaboard. Why do people always seem to be much more prepared to accept the banal falsehoods than the fantastic truth?
