When in Downtown Yonkers, check out the Science Barge! Run by the Groundwork Hudson Valley, it is a floating learning center which models examples of sustainable methods of living. Some examples include sustainable agricultural methods and technology.
We were taken on a tour by Bob Walters, who is the director of the barge. He has some great stories about Yonkers including how Yonkers used to be the "pickle port" of America. Anyway, its a must visit! Check out their site, http://thesciencebarge.tumblr.com/
Check out a new blog on downtown Yonkers called "New Yonkers" It has a nice post on the Science Barge. http://newyonkers.tumblr.com/
