There are a number of towns or villages in Pennsylvania named Smoketown, so in the early 1900s they decided to change the name to Plainfield, to eliminate any confusion. However, when a place has been called one name for so long, it can be hard for everyone get used to the change. So many locals continued to call it Smoketown, or used both names Smoketown/Plainfield.
Regardless if you call it Smoketown or Plainfield, it’s very easy to drive by in the blink of an eye and miss what is left of the village.
