We have some 60 year old Manitoba Maples in our back yard – When faced with the question – tree house – or tree “tent” – our granddaughter had no hesitation enthusiastically choosing the Tentsile Stingray over a wooden tree house, for a backyard retreat when visiting Grampa & Nana. After an easy set up (with a couple calls to the fine folks at the Utah store) – we enjoyed a couple of very restful sleeps in our backyard retreat!!!GAT
