Rent a car at Leverick - we did it last year and we're doing it again this year.

I think Cooper/NS/Anegada is a good idea - on the advice of a couple of buddies on here, we had a fantastic sail from Cooper to North Sound last year, on a tack outside the Dogs until we lined up with Necker and then just tacked into the NS -- one of the best sails all week - the sail to Anegada from NS was the next best.
