A fire in Hickory Tree has kept fire fighters and the U.S. Forestry Service busy over night and into this morning. About 20 acres burned on Troublesome Hollow Road in Sullivan County from fire that started around 6:00 last night. Forestry officials say they will wait until they’re sure the fire has been completely extinguished and then they will begin investigating the cause of the fire and determine exactly how much of the forest was burned. Just a reminder that fires can get out of control very quickly, so there is a burn ban in our area until May 15th. If you need to burn debris, you must first get a burn permit from the Tennessee Department of Agriculture.
