Discription of Events: Driving West on US 38 towards Pendleton this morning, a black Jeep was behind me, I was behind a Webbs drywall van, and they were behind a truck pulling a trailer (open like for hauling mowers ect) In a no passing zone and with curves ahead, proceeded to pass not only me but the other two vehicles as well narrowly missing a truck and other vehicles coming around the corner. As I entered into Pendleton, they hadn’t made it much ahead as were stopped at stoplight at 38/67 intersection. I proceeded to follow them out of Pendleton where they turned into the Pendleton Correctional facility on the east side of 67. They were reckless in their speeding, endangering not only their life but mine and the several drivers/passengers in the other four or five vehicles.
