(Portland, OR) -- A tree is back at the world's smallest park. A couple of weeks ago, someone stole the tree from Mill Ends Park in Portland. The Parks and Recreation Department has planted a single Dwarf Alberta Spruce tree in the utility pole-sized hole that is Mill Ends Park. The park was created in honor of Dick Fagan [[ FAY'-ghen ]], a columnist for The Oregon Journal. He wrote of a leprechaun who lived in the hole. The park is located on Naito Parkway next to Tom McCall Waterfront Park.
