We explore, push and occasionally leap over borders and boundaries of all sorts. We visit the stone markers placed along D.C.'s border in the 1790s and hear what's being done to protect these little-known monuments. We hear the tale of the first Jewish aviator: a man who defied long odds to become a pilot for the Wright brothers. And we find out why Virginia officials are planning for a future in a region they're calling "SuperNova."
