Delmar, MD, is a small town with an interesting past that marks part of the historic origins of the Mason-Dixon Line (1763-1767). Straddling both the Delaware and Maryland borders, you can easily be in two places at once! Head straight to Middle Point to see the Mason Dixon marker for yourself then spend the rest of your time exploring one of the public parks or heading to the U.S 13 International Speedway drag and car-racing track.
