Was on my way from the Lusk, WY Supercharger, making my way to Mt Rushmore, and my last stop was at Custer, SD. I arrived at the charger with 3% but found that the supercharging stations were inaccessible due to construction around that section of the parking lot. Especially due to snow, not even the back side of the chargers were accessible. The map on the MCU was showing that the charger was accessible and two chargers were already being occupied, but that was not true on arrival. I already notified Tesla about the issue, but not sure if they have updated just yet. There are, however, level 2 Tesla chargers found throughout the town that are accessible. I was able to access one at the Custer Area Chamber of Commerce & Visitors Bureau.
