Isn't Maryland's official state sport jousting?
It is, sort-of. The version of jousting, is the "jousting games" version, such as lancing a ring. It's not the "full tilting at each other" kind. Also, there's been a strong movement to replace it with Lacrosse as the official sport.
I think last I heard, they compromised and made Lacrosse the official modern sport, and Jousting the official historical sport... or something like that. Might be worth googling.
