Sorry Dog was actually at the site of the tree strike at Mrs Benson's house.
I think he said the trees were 60-70 feet tall. There is a photo somewhere.
Sorry Dog is, I think, who I got the 40 or 50 foot height from. I figured, since he's near the site, he could take out an old camera range finder or something and double check the height, since trees in central Alabama are often over 100 feet tall.
