What defines a town as “bordering” the Wyoming-Idaho state line?
Generally, a town is considered bordering if its municipal limits or its immediate surrounding community infrastructure directly abuts the state line. While some towns might be split by the actual border, others are positioned just on one side, yet their daily life and economy are intrinsically linked to being right next to the adjacent state. These towns often share services, populations, and cultural ties across the invisible boundary, creating a unique cross-state identity.
