Why?

Virginia is a hop skip and a jump from my house.  I have a VA non-resident LCH.  I am there a lot.  I carry there.

Hey, you want to know a fun travel plan?  Take your gun on an airplane trip from my house to Reagan National Airport (in Virginia) via the Metro.  Glenmont Station on the Red Line is walking distance from front door (in Maryland) and odds are the subway is on fire somewhere so I'd have to eventual de-train to a city bus for part of it (Warshington DC).
