I want to know the brand of chainsaw chain they used that got through the concrete...
Concrete near the bottom of the tree would have been fairly obvious, one would think. I have a tree in my yard that has a hollow spot, but it’s about 30 ft. up.
Anyway, I don’t know how big the hollow part might be. I know it’s hollow because I used to see lots of bees flying in and out, but they seem to have gone away. Had the tree trimmed a few months ago and they didn’t recommend doing anything with it. (fingers crossed)
