The 2nd Annual Golden Gate Express Garden Railway is open at San Francisco’s Conservatory of Flowers. The garden features miniature versions of the city's most recognizable landmarks, buildings, and of course, a train! Plus, they are all made of recycled materials. The exhibition is open until April 18th, but if you can't go, you can see more pictures at Laughing Squid. Link
