I'm leaving for a trip to South Africa on Monday, and want to take one with me for the 17-hour flight. Obviously it is too late to order online. I've called a few Apple stores, but nobody has one in stock. Any advice on best store to find one? I am in central New Jersey, but will be driving route-95 through Philadelphia-Baltimore-Washington on Sunday, to fly out of Dulles on Monday. Or am I SOL?
