This cold weather has me thinking of indoor gardens. In Madrid is the most beautiful indoor JUNGLE in the main train station, Atocha. The plants are watered every few hours by these big misters, you can see them in action here above. The original station that was built in 1851 was destroyed by fire, and this new station was built in 1892 by Alberto de Palacio Elissagne and Gustave Eiffel (recognize that name??).
