Thursday, April 4th, 2013 — The sinkhole first opened up in August of 2011, a relatively small thing, 2 feet wide and 5 feet deep. But in the 15 months since then, Florida couple John and Tina Furlow have watched helplessly as the sinkhole expands, threatening to swallow their bedroom. "Now it’s approximately 8, 9 feet long," John Furlow told CNN affiliate WFLA last month at their home in Hernando County on Florida’s west coast.
