China builds two new coal plants a week that are powered by american coal(thanks gubmint!)?????? ...and I can't buy a gas powered lawn mower in this once great state!
Make sure to keep juice in the wire so the copper gang will get a real buzz outta their night(crawl) moves.
Did you see the pretty zebra stripes out pinacate way!? WOW!
