Remember how the ice cream truck used to play the same song (over and over and over) in your neighborhood every summer as it drove around? Growing up just outside of Detroit, I thought that was the only way to buy packaged ice cream without going to a stand or store. When I moved to Chicago, I discovered a second option: the ice cream cart. These are pushed around the neighborhood with bells instead of music, and they're actually more common where I live now than the trucks of my youth. Leave it to London to bring about a third option: the amphibious ice cream van. If only I had a boat.
