[Elecraft] Ham shop nr Washington DC

[Nick Verbeek]

I am flying this friday into Washington (Dulles Int'l), rent a car and will drive north towards Harrisburg (PA).
All for only a short visit.
Is there any respectable Ham radio shop in the area where I can do some shopping without going into too much of a detour?
I am actually looking to buy a Sierra mobile whip (or similar)

Anybody from the area with a suggestion?
