The possibilities of winning the grand prize had folks dreaming up how they would spend the newly acquired cash. “Buy a house, live my life, third pick up some woman and live my dreams,” said Abdul Khaiyat. “We’ve been pretty thrifty with our money so we’re pretty well set. We just try to see how much good we can do,’” said David Kniess.
