During the overnight hours of Oct. 17, an automobile jumped the sidewalk at Wisconsin Avenue and P Street, NW, striking the facade of the corner store, L’Enfant Gallery, known for its furniture and sculptures as well as artwork and maps. The gallery is packed with items for home decor — and, apparently, for a new, unexpected use: traffic barrier. While the store’s glass was shattered by the impact of the wandering car, the large stone lion in front of the store stopped the car from going through the window front and seriously damaging the store.
