Two teens were plucked from the river by rescue crews Monday after they were swept downstream by swift currents on the Barren Fork River.The youths, both described as teen girls, had entered the river at the boat dock behind Rocket Park off Beersheba Street. They were reportedly just planning to float around in the normally placid water as they had floatation rings with them. However, once they were in the swift water their floating rings were swept away.
