I would have to rate it high, since women were granted full suffrage in that state, and they were first in government. When it became a state, it caused the others to follow equal rights too. Without its history, I would believe that the 19th Ammendment of the US Constitution would not pass on time. Fine nickname.

The first state or territory to grant the vote to women. Of course, there were few if any women in Wyoming at the time, so the Wyomingites weren't risking much.

The equality state? An obscure reference to a small part of their history. You'd think they could come up with something better.
