The Greenhouse Tricycle is in an amazing show about bike advocacy at the Aldrich Museum. It is called Bike Rides: The Exhibition and is co-curated by David Byrne along with Aldrich curators Richard Klein and Mónica Ramírez–Montagut. They collaborated with a local organic farmer and to grow all kinds of winter greens inside. The visitors are watering and tending to the plants and hopefully eating them too. It runs from September 26, 2009, to January 17, 2010, and they've published a nice catalog to go with it.
