Hi Andy

Your approach is similar to mine. Cover the most probable things. You mention that you travel to DC by both train and car. I assume you are going to meetings with you clients. I've been around DC a long time, and have had a couple of experiences that you might want to include in your plans.

In 1968 during the riots, public transport shut down. There were only a few safe routes in and out of the city, and only by car/motorcycle/walking. I don't see anything like riots in the cards, but even a small terrorist attack would, I think have the same effect. You might have to either walk a long way, or hunker down in your client's building.

I was also in the Pentagon for a meeting the day when, during a snowstorm, an Air Florida jet crashed into the Potomac right next to us. Didn't make it home until the next day. The bus that was supposed to pick everyone up never showed. . .

It sounds like you have everything pretty much covered, but if you haven't thought about what happens when you are in that meeting in downtown DC, it would be worth some extra thought. And given the increased security in some of the buildings, you may not even get a SAK in with you. I've seen several confiscated. Makes planning harder.
