Jonathan Hammond, owner of Alpine Tree and Shrub Care, removes dead limbs from a tree at a client's home in Westminster, Colo. Fall is an excellent time to give your trees a good once over before the winter storm season begins. Dead branches _ or the entire tree _ can come down in a storm. Be proactive, arborists say. It's a lot cheaper to have the limb cut off than to fix your roof, said Hammond. (AP Photo/Ed Andrieski)
