"I thought that because fewer wolves meant more deer, that no wolves would mean hunters' paradise. But after seeing the green fire die, I sensed that neither the wolf nor the mountain agreed with such a view."
Aldo Leopold
Walking the mall takes only a couple hours at most, if you take your time. Not too far north of there is a retail location for Penn Camera. Nice folks. Check out the Smithsonian exhibits. Other than that, I can't comment on much since that's pretty much all we did. Oh, if you're tempted to eat at the Austin Grill, don't. Cuba Libre was good, as was Zengo if you can get a table. They tried to turn Kal Penn away before the manager chewed out the hostess. The food is really good if you can put up with the arrogance. Chinatown has some good shopping and lots of food joints.
Don't forget to piss on the IRS building as you walk by. It's a DC tradition.
