I have no idea where this came from but Job, my child who doesn't like heights, decided to place our hammock high in the cherry trees.  He even measured it.  It's 12 feet off the ground.  He comes home from school, has a snack and climbs into his hammock for about 1/2 hour.  Sometimes he just sits, other times he has his binoculars, and others he brings the iPad so he can read.  We have a book on there that has captivated his attention.  He's rigged up a little "elevator" so that he can haul his dinner or any item he wants with him in his hammock.  During the day if I can't find him I check the sky hammock and often times that is where he is.
