Jellyfish all over Dahlgren/King George Area

We tried tubing in six spots: upper Machodoc Creek, middle of Potomac river, north of Nice Bridge, and 3 points north of Mathias Point. All had Jellyfish. One almost got me, I scrambled out of the water just in time. It had turned itself nearly up-side-down so that its 2-foot tentacles almost touched me. it has a dome of about 8 inches
