1. Maryland's "living insignia" are the most interesting of any state we've seen: the state bird is the Baltimore Oriole; state butterfly is the Baltimore Checkerspot; state crustacean is the blue crab (which is also the state food, but by then the crab is no longer living, of course); state reptile is the diamond backed terrapin; and one of the three state mammals is the Chesapeake Bay retriever (a dog -- the other two mammals are calico cat and thoroughbred horse). The state sport is jousting.
2. The state is considered to be the birthplace of religious freedom in America, because it was formed as a refuge for persecuted English Catholics in the 1600s.
3. The counties east of the Chesapeake Bay, which splits the state, are called the Eastern Shore. At one point, the state is only 1.83 miles wide.
4. Most of the earliest European settlers arrived as indentured servants.
5. Maryland currently has the highest median household income of any state.
6. The state's geography varies widely, from mountains in the northwest to flatlands near the coast.
