At Native Voices, which is a First Nations (union) theatre company in LA on the grounds of Griffith Park's Autry Museum of the SouthWest, the top of each show includes appreciation to the land, to the elders, and to the indigenous local tribes. I love this practice, and when I produced the Diversity Awards for the west on behalf of AEA and then AEA/SAG/AFTRA, I always made sure this was included at the top of the show by someone from the Native community regardless of where we held the event. It's such a great thing to remind people that, well, they were here first.
