Hello all. Will be visiting D.C. March 11-12 (Sunday-Monday). We'll be hitting spots all over the city, so unfortunately we'll have a car. Are there any lots (paid, not free) near the Lincoln Memorial and near the midpoint of the mall, near the Smithsonian? We're willing to pay for the spots since we'll be coming from other areas around the city. (And please, while we appreciate all advice, please don't recommend ditching the car and using the metro. We simply don't have easy access to it ... or anyplace to leave our car while we would be using it.) Thanks!
