AI really only has one bar,,,during big swells, all the wave action breaks on that one bar,,,there are a couple areas where, like the wedge (just south of the inlet) where there is a persistant long bar that stretches a good distance from the beach out some 500 yards plus,,,use to paddle across from stinky beach and surf it when I was a kid during big Nor easters or huge se swells,,,when its perfect you could ride the wave all the way in from over 500 yds out,,,areas on the outer banks have two bars, but that second bar is way out there,,,during big swells, you can see it break on that second bar.
