Thieves take only greenery from "world's smallest park".

The lone tree in Portland's smallest park vanished last week, leaving a gaping hole, according to Portland Parks and Recreation.

Mill Ends Park is only two feet in diameter, made up of just a small patch of grass, a few plants and the one tree. It's not only Portland's smallest park, but it's also listed in the Guinness Book of World Records as the world's smallest park.
