Broadway operates with 17 union contracts that are held with 14 different unions. Each one has different types of interaction, whether shair and wigs or make up, or costumes or stage hands. So we had to work with them and develop the protocols that made them comfortable. And as i'm sure i said to you a last october, we could not afford, with the cost structure that broadway lives under, to open and then close and reopen and then close. We waited until enough people were vaccinated and we had all of these protocols put in place that we felt we could deliver a safety for cast crew and audience.
