Did so.
Check out the District of Columbia.
I don't even want to go NEAR there with a firearm.
That's why I suggested 301; gas up in VA and drive through to Delaware -- keeps you off the I495 that could push you West if there's a major accident on the Eastbound side. Keep up with traffic, but let the hot-shots pass and pull the cops. Case the weapons and ammo separately and out of reach while driving. Or find a FFL and ship them ahead.
