  "description": "Based on a photo of the Angla windmills against the setting sun in a slight winter haze. This row of 5 wooden windmills is a landmark on the island of Saaremaa (Estonia's biggest island). My original photo and other photos of the windmills can be seen here: <a href=\"https://outgoing.prod.mozaws.net/v1/02b00972f38bda06bac741c9e10278bd5ff105e60bdc262a9fa3743298202ede/http%3A//ottodv.com/angla\" rel=\"nofollow\">http://ottodv.com/angla</a>"
