how would you describe the three main groups of people in the story ?

There is the original group. The party consists of Duchess, a saloon girl, Mother Shipton, a madam, Uncle Billy, a local drunk and thief, and John Oakhurst, a poker player, who won a lot of money from the people sitting on the secrete committee. There is the young runaway couple, Piney Woods and Tom Simons, heading to Poker Flat to get married.
