Funny you bring this up at this particular time.
I just wrote an article (subject to editing and revision) that I'm going to see about getting published in some small newspapers or area magazines in Cobb, North Fulton, and Cherokee Counties.
The article is about tort liability for land owners whose trees fall down and cause damage.
The bottom line is that there is, these days, a duty to keep an eye out for sick / weak trees that look like they are at risk to fall over or have big limbs drop off of them. And there is a duty to take down such a tree carefully, rather than sit back and wait for it to come down on its own, where it might crush somebody's house, car, or land right in the middle of a busy road where someone will come along and crash into it a few minutes later.
The last time I used a tree service, it was a guy based in Canton, I think. Let me think of his name.... I had it stored in the address book of my last phone, but it died and my new cellphone doesn't have him in it.
If I find it, I'll let you know.
