Erin is a suburb located northwest of Milwaukee. The Town was created in 1846, before Wisconsin became a state. Many of its roads are named after Irish places.
While Erin has a big history in agriculture, it has more recently taken a suburban influence with new construction found around the area. However, there still are many higher speed roads for getting to the city. Additonally, I-41 runs through a neighboring community which helps for easy commutes. It is neighbored by Richfield to the east, Merton to the south, Hartford to the north and Ashippun to the west.
