This is Betsy Ann and The Mayor of MASH Town. They played the paper game MASH and they got Shack so they moved out west to the desert and set up a town. Right now they are the only folks in town. That is why the mayor got to be The Mayor.
Betsy Ann wishes they would have got mansion, apartment, or house but lady luck choose them this here shack and that is that. She is plotting to kill The Mayor and run away with the band of Native Americans (Indians) that sometimes comes to MASH Town to trade coyote furs and tobacco.
