Save my tree!!!

We are having concerns with the big tree in our front yard. I love that tree and want to keep it at all cost! The kids have grown up swinging in that tree. It took forever for us to even get the ropes up in the tree to get the dolphin swing hung 10 years ago. We are doing our best to design the front porch steps to come down at a different point to save my tree. I know it will all work out, but I gotta have my tree... :-)
