Not sure how many of you know this (we just found out, too): since 2001, a slew of New York City subway cars have been dumped into the ocean up and down the east coast of the US to help create artifical reefs. Good Humor trucks have even been used. This seems insane to us, and some states have decided to stop this weird practise. Read about it here or read about unwated toilets in a similar experiment on the west coast.
