There’s an ice-cream truck that circulates through Rogers Park in Chicago all year round but only after about 10 or 11 PM. I’m surprised no cop has ever stopped this one for a look-see.
In the early 80’s there was a snow cone truck that came around where I worked. The bosses all thought that it was so popular because it was operated by a young lady wearing short shorts and halter top. The real reason was that she would add a shot of rum for an extra dollar!
