We live in Madison Wi and drove to MSP last weekend in our Model S to visit our son and grandkids in Golden Valley.--great road car. No problem with the superchargers in Eau Claire or Mauston. We had to recharge to be able to get through the weekend and back to Eau Claire. The service people in Eden Prarie were very helpful and made the trip seamless. We will make the trip a few times a year and wonder if there are any Tesla owners near Golden Valley who would let us use their charger? Obviously we would be glad to reciprocate if you came through Madison. We live close to downtown and within walking distance of the stadium. It would be helpful if Tesla would install outdoor chargers at their service centers since many of them are in urban areas. p.s. Watch out for MSP potholes!!
