Icon 077. Car Ferry
Imagine the following scenario. You have a car on one side of a large body of water and you need to get it to the other side for any number of reasons. Perhaps you see a basket of puppies over there. Or a large bucket of chicken. In any case, the obvious way to get your car across is to go all James Bond Jr. on things and press the "turn into submarine" button. Easy peasy. Or, if you want to make things difficult, you could just take a ferry. I made you an icon for the latter.
