I'm hopeful that the 2018 supercharger map might show one for Willow Springs or Cabool. Nothing wrong with West Plains and it is definitely the best place for area amenities but the two cities above would be at the junctions of US 60 and 63 and could still serve traffic headed to West Plains, MO or Jonesboro, AR (another place that could and should get one eventually).
@ efusco, I looked at the ChargePoint page the other day to request some chargers down I-55, but they seemed to want contact info for specific locations and I haven't had any conversations with anyone. Did you have to put contact info or just recommend the cities in general? I may need to look again.
I do think West Park Mall in Cape Girardeau, would be a great place to have some DCFC stations, though. Decent size college town.
