Thanks to all so far! We'll update with what we find out in case anyone else finds themselves in this kind of odd situation . . .

Given the chance to put together our wedding as we really want it, my fiance and I are attempting to plan a weekend in a national park culminating in a picnic/BBQ reception. Our biggest hurdle is that we have our hearts set on a location that seems to be near exactly no kosher caterers who can do what we'd like - does anyone know of a catering company in the VA/Washington DC area (or even a bit further afield!) that caters decent BBQ?
