I think what Paladin meant is that, if you are going to a place where it's illegal to carry a knife with a blade longer than 3", you probably shouldn't expect to find any good knife deals. I think you'd be better off just seeing the sights in DC and buying your knives off the forums. I travel to DC once a year on business, and being a big knife guy, I didn't have anything that I could legally carry there. I bought a small knife (Spyderco Yojimbo) just to carry whenever I'm in DC.
