Peggy Joe was able to evade capture because of her costume:
She convincingly dressed as a man - including a realistic beard. The note she would pass the bank teller said:
Authorities thought they were looking for a soft-spoken man, whom they nicknamed "Cowboy Bob" (named after a childhood icon from the 1970s and 80s).
"This is a bank robbery.
Give me your money.
No marked bills or dye packs."
Dramatizing a real person's life can be tricky - or even controversial. Mostly because it's hard to condense a person's life down to two hours.
The creative team loosely took the descriptions, actions, and family of Peggy Jo Tallas and created a new character based on this mythology. This choice allowed them to shape the character of Cowboy Bob however they wanted - in order to focus on the show’s themes.
Here are a few things that are mentioned in the play. If you aren't familar with them, then this might help you enjoy the show even more.
