Here is what my verymost local municipal tree looked like before the big trucks pulled up yesterday:
The yellow arrow on the upper left points to the problem.
I sat in the living room for the 20 minutes it took to address the entire situation. The guys would sling a rope around one limb to act as a pulley for another, drop a few leaves with some sawdust, then swing a branch down, canopy first, to the lawn. A chipper parked in front of the house dealt with the remains immediately but I had time to see the round splotches of disease on all the leaves too high for me to see normally. The tree is nearly 70 years old so I guess it's not a surprise, but I'm sad to think I might be seeing the last of its long years.
They didn't cut the problem limb itself - they'd need a bigger truck for that - but they did cut away any branch that so much as thought about the roof of the house, thereby avoiding any liability risks in future. Which leaves us with this:
The house feels so barren.
On the bright side, maybe now I can get solar panels?
