DC Circulator

If the metro system is just too much, then maybe the Circulator bus will be a comfort.  The Circulator only has two lines, an east-west yellow line, and a north-south red line, intersecting at the DC Convention Center.  The yellow line runs from Georgetown to Union Station, and the red line runs from the Convention Center to the waterfront at Maine Avenue.

One advantage the Circulator has over the Metro Bus is price, the Circulator is just $1, and transfer tickets are available on board that let you continue on the other line.
