Equestrian
This is not something that you'll get to see too often here in Meridies, but yes, it does exist! http://www.cavalry.meridies.org/ And it's worth the wait. Gulf Wars is one of the main places to see the horses in action. For obvious reasons, we don't want people to be in battle versus cavalry exactly like in medieval times! So no, this is not going to be a show like you'd get at Medieval Times, and we won't have jousting against persons. Instead, the horses are trained with things like Quintanes.
But it does appear that the group gets together for practices in Fort Valley GA and Mentone AL.
