Seriously. If the trees are an impediment to what you REALLY want to do in your yard, then modify the yard so you can do what you want. Most people struggle to get some kind of tree cover over their houses, but you've moved into a place where not only are the trees well-established, they've excluded all other activities. It's time to decide what you want to do, and where the best place is to do it. Then take out the trees that are in the way.

Pull up your socks, Janie. Tell those trees who is boss! :)
