Hey Mary. Ocracoke is so awesome in August, Im actually planing a trip there around September. The cheapest way I know to come close to here from New York is the ChinaTown bus http://www.chinatown-bus.org/ It doesn't go all the way down to Okracoke, but it does come to Norfolk, Virginia, which is 2.5 hours away maybe, and its only 35 bucks. From there you could then rent a car. kinda all I got...good luck tho!!
