I am hoping that tree falls down in a good windstorm. It's dead, and out where it will not matter which direction it falls. Nothing will be damaged. So, I have been waiting it out.
In the meantime, I'm watching YouTube videos on tree felling for my particular case. Have not yet found a video with what I'm dealing with but learning a lot about tree felling and gaining more knowledge. Never too old to think I know it all.
Also, my longest chainsaw bar is 16 inches. The tree trunk is wider than my bar. I'm estimating maybe 22 inches round where I would cut it. I have done that, and bigger, trees before without any problems, but this tree has rotted wood going into the trunk, so I don't know how strong/stable it will be. It's the unknown that gives me pause.
