The top of the new swings at the lower farm, where our guest house is, is fourteen feet up. It would have been fifteen, but the frame was too heavy to lift entire, so our carpenter (Bud) backed off the mortices and we raised the posts separately, then used our friend Tim’s tow truck to lift the lintel. The truck could only go up to fifteen feet, and of course the tenons added another ten inches or so, so the posts had to lose a foot so we could set the beam. No problem, the arc still sends you up into the neighboring tree tops. Make a reservation on airbnb and come try it yourselves!
