TVA employees supported by an armed guard entered the private property the government agency is condemning shortly before 1 p.m. today. The environmental study team was from Knoxville. They said they weren't testing, just observing the "natural features." The officer in full body armor wouldn't say where he was based, just "Hamilton." They crossed Gunstocker Creek and onto Project Viper, TVA's $300 million new secret city in Georgetown, around 2:45 p.m.
