CONROE, Texas – A 63-year-old man and his dog fell Sunday morning into a 50-foot ravine in Conroe, officials said. McManus and neighbors said he was searching for his dog Sandi, a 15-year-old retriever that he rescued in 2006. A large group planned to launch a search for the dog Sunday afternoon when McManus decided to find a way to the bottom of the ravine. The Woodlands fire arrived, set up a tripod alongside the ravine and a firefighter repelled down to McManus and Sandi. Over the years, the land has eroded so badly that McManus’ fence is almost fallen into it the ravine, she said.
