Officials With Observation Knob Park In Bristol, Tennessee Have Ordered All 178 Campers To Vacate The Park By March 15th. This Will Allow Time For Inspections And Repairs By The Tennessee Valley Authority, Which Leases The Land To The Sullivan County. This Year’S Operating Season Will Run April 1st To October 31st With Several Changes, Including More Short-Term Camping And A New Seasonal Rate Of $300 Per Month.
