May 1 through 3, one of the best craft fairs in the Northeast takes over the grounds of Lyndhurst Mansion, and we built an entire weekend around it, a historic estate hotel, a waterfront dinner on the Hudson, a bottle of small-batch bourbon made here in the Hudson Valley, and a night out in Dobbs Ferry that does not know when to quit. We are giving the whole thing away to one winner. But whether you enter or not, this is the weekend blueprint worth bookmarking.
