My kids are wanting to try and build a tree house/club house. The tree they want to build it in has a deep 'V' in it that is very close to the ground. I've told them that I'm afraid small critters may be able to jump/climb the short distance into the place where they want to build the house and may end up being a nuisance or even dangerous. I always envision tree house as being high up but I'm also afraid of them placing a tree house in a tree that IS high up and then falling out of it. Do any of you all have a tree house?
