It is my intention to reach those outside of Westview.
The Vision sees Agnes’s car stopped at this intersection, where he questions her about the strange events going on in town. In-universe, this is the intersection of Rolling Hill Dr. and Ellis Ave.
The entrance to the neighborhood of Meadow View in Williamson, GA, was used for this more realistic location. The actual streets are Rolling Hill Dr. and Williamson Zebulon Rd.
In the following episode, Monica penetrates the barrier around the town and re-enters Westview via this road.
