So, in Woodstock, Vermont, where my office is located, there is an electric trolley project that we've been working on for the past 2 years. What's sort of unique about this electric trolley is that it's run on cow power and cow power, cow manure. And the program is actually run by the State's utility company, CVPS, and they have a cow power program where they have participating farms and they are outfitted with this anaerobic digester infrastructure. They collect all the cow manure and they filter through it and digest it, and then the biogas that's given off is then converted into electricity. And so, this electric trolley is then charged on this electricity, and it's kind of a unique program.
