Most ACX choreography is done in house now so it's kind of an ongoing thing. They have some choreography dates but a lot of it is done at practice now.
Choreography the end of June, music at the same time. Until then we work with stunt groups and try to get a feel for what to tell the choreographers when they come out.
last weekend of july for us =) with 2 months of practices before hand so choreographers (and us coaches) have a good idea of where the teams stand skill wise =)
