I know it's hard finding a good spot of flat land now that the choicest spots have all been fracked for methane and are no longer stable - thanks, 'green' energy shysters! - but what else were ya gonna do with all that space under the solar panels?

By-product? Free showers for the homeless with that waste heat. Yay?
