Why do most Powerball winners seem to come from out west?

Me and my coworkers and friends keep wondering why almost all the Powerball winners come from the central, midwest and western states. Does anyone know why? It is extremely rare that someone on the east coast wins the jackpot. Any comments on that? :-)
