The Maine Warden Service says the search is continuing for a missing hiker in a rugged section of the Appalachian Trail, but a more intensive search effort may have to wait for the weekend. Geraldine Largay of Brentwood, Tenn., has been missing for more than a week. The warden service said in a statement that the logistical and physical challenges involved in scouring the remote terrain has restricted its ability to use volunteer searchers who do not have required professional training. Officials said they are planning for a more intensified search when more resources become available in the upcoming weekend. The 66-year-old Largay, an experienced hiker, contacted her husband from the top of Saddleback Mountain on July 21 but failed to meet up with him as planned the following day.
