We have two trees on our front lawn that really should be removed...one is dead and falling apart... we had a lot of the biggest branches lopped off a year ago and then the tree guy vanished before finishing the job (we hadnt paid him yet so no worries)
So it's not in any immediate danger of killing anyone.
The other is valinetly trying to stay alive, throwing out new shoots but it is on it's last legs (roots?) I hate to take them down , and not just because of the $600 we've been quoted, the birds love them and the hollow trunks are full of nests
