>>The Thousand Island area of New York is a wonderful place to visit, so much to see and do besides the lighthouses. <<

I'll second that - and you get Sunken Rock to boot! The whole upper west coast of NY is a beautiful area w/ lotsa neat lighthouses and early American history.
From Charlotte-Genessee northward. Great spot for a reunion (though its hard to imagine a hoard of a thousand people moving through the area en masse.)
