Since 1947, more than 12 million cards and letters have been sent to Loveland, Colorado's post office to be hand-stamped and mailed to the lucky recipient. In 2014, they received more than 150,000.
"That's from all around the world – in fact, 110 countries, 50 states," said U.S. Postal Service spokesman David Rupert. "It's amazing how this is a worldwide phenomenon.”
While Loveland is the biggest, it certainly isn't the only place with a romantic name and a remailing program. There's also Loveland, Ohio, Valentine, Nebraska, and Cupid, Maryland.
