Nice story, and good to hear from another Kansas City area Tesla owner. I'm a bit late discovering this thread, but I made a similar trip in February. I picked up my beauty at the Denver service center and drove home(about 600 miles plus a few demo rides) to Prairie Village in two days. Along the way I charged at a Walgreens, two KOAs(Limon and overnight in WaKeeney), a friend's generator repair shop in Salina, and a Westar in Topeka. It was cold, so I had to drive slowly to conserve energy, but managed about 280 wh/mi by averaging about 60 mph. Got home with 16 miles showing--a little range anxiety, not knowing exactly where empty would be.
Next road trip will be St. Louis to get the punch list taken care of--does anyone know when the St. Louis service center is really going to open? I think bluefuego said he was at a get-together there in March.
It sounds like we might have as many as ten Teslas in the KC area now. I will have my Model S, along with several other EVs, at the Prairie Village Earth Fair at Shawnee Mission East on Saturday April 13.
