Tubing Down Shenandoah River

Hey guys I'm trying to get a group of tubers going Saturday July 26th down the Shenandoah. We're going to do it renegade style, bring your own tubes. I spoke with a friend at work and there's a solid route out past Purcellville. My plan is to drop everyone off at Lock's Landing tubes and drinks ready to go. Then bring all cars back to the overpass. Then drivers hop in one car and go back to Lock's Landing and takeoff. Who's with me!!
