Beautiful tree, FG. I can see why anyone would want to make it their home.
When we lived in the country, we had one of those in a tree on the property next to us. My DD, 4 at the time, played there with the neighbor kids. The kids were throwing rocks at it.
I called the county and they had it taken down, free of charge. Actually the neighbors took it down themselves, after the County told them to do so, and saved it. All the monsters were dead and gone though.
Before it was down, I had opened my front door and one flew into my house, but turned around and left without attacking anyone. I didn't see this...my DH was standing next to me, saw it and didn't tell me, until it was gone. He knew I would have had a heart attack.
I'm allergic to honey bee stings so I wanted no part of these babies..

I did see one and they were really BIG!!! These are the kind that can knock you right off of your feet if they hit you.
Too bad it was in your yard and you had to pay for removing it.
