What is a billboard but an uninhabitable building beside a road? For a new welcome sign for Las Vegas we propose a 10-mile spiral that sits just over the first hill on the valley floor. Its a place where one can play slots, roulette, get married, see a show, have your car washed, drive up an observatory and ride through a tunnel of love, all without ever leaving your car. Its the first gamble in and the last chance out, a compact Vegas enjoyed at 55 miles per hour.
