Popular Mechanics has compiled their top ten list of tree houses. And these are not the little forts I had as a kid, these are more like what you see on the home improvement cable channels. Pretty cool, and pretty expensive. I wonder if anyone sells those lumber-to-tree brackets online. I would like to build a viewing platform up in a Chestnut Oak on a high spot to catch those winter views but I do not want to just nail into the tree.
I did have one nice tree house in a huge oak in Atlantic Beach, Florida when I was a kid. Given our location two blocks from the beach my step-dad and I opted to screen it in. Man, I miss that tree house, it was nice. It was actually in a huge fenced-in yard of a house that we had rented when I was a kid, a good half acre. But ten or fifteen years ago they built another house in that side yard and I do not think that huge oak survived it. No one has a big yard down there any more, they manage to fit a skinny & tall McMansion into any old side yards.
