Description Sluglines forms in front of the restaurant Heritage India (closed now) on 19th street between I street and Pennsylvania Avenue at 854 19th St NW, Washington, DC 20006 (https://goo.gl/maps/BRsy77PixC62). Drivers heading south pull to their right and pick up slugs for Horner Road and Tackett’s.
