I thought you probably knew - or you wouldn’t have been reading this thread!
But a lot of people, even if they know about the games played by the South American and Mexican Indians, and then all the way north to the Algonquins, don’t realize that the Florida and Georgia tribes (which didn’t have a particularly spectacular civilization) had these games too.
Hohokam ruins in Arizona usually have ball courts along with other evidence of trade with the Mexican Indians (Casas Grandes is just south of New Mexico and is the northern most Mexican culture ruin). At several San Pedro River valley ruins, the ball courts were very plain and easily mentally reconstructed. Neat stuff.
