Easily best. Unique in the States; geometrically complex but not complex as in all the 1s that incorporate actual pictures (e.g., seals), and also distinct from the US flag itself. The seal flags are boring despite using something complex - esp. as almost all of those seal-flags are on blue fields. They all look the same. You can easily sketch the MD flag very accurately; 1 should be able to do that w/colors, not to mention clearly distinguish them from others. It is indeed heraldry-driven, the colors of the Calvert (founding governors) and Crossland families - black&gold & red&white, respectively. 1 thing I can be proud about as a MDer; all the other things to be proud of are way in the past.
