I have a tree in left front of my house at 40 nelson st that was suppose to come down 2 ys ago because has lots of cavities . A big branch hangs over my yard from that tree and it is going to fall any time. I worry because under that branch is my kids play area. Definitely not safe, whenever it is a sight bit of wind they are not allowed in the play area. I know how damaging a branch can be from one of theses trees. a branch from a tree across the street me has been losing it's limbs, and it has damaged fences, and just recently damaged my husbands car. I would like this tree removed or trim, but something has to be done before someone gets hurt.
