Popular Point campground is one of my favorite places to pitch a tent in the Jordan Lake area.  It's often not as crowded as the others at Jordan Lake are, esp., during the week and outside of holidays or summertime.  The views are nice, with sites next to the water.  Tents and RVs can camp in the same areas.  We normally camp in a tent here, but never in the hottest part of summer, which is most of the summer in the Piedmont area of the state.  You gotta go up to 3000 feet, as in the mountains of NC, for a cool weather experience in summertime, but for a night to get away from your regular routine or a weekend when the weather is nice, this is a suitable place.  Locals like it because the drive isn't far from Raleigh, Chapel Hill, Durham or Pittsboro.
