I think I've found the new Ellensburg supercharger location! Didn't snap any photos, which I now regret, but it appears as though the Taco Bell just down the street from the existing Ellensburg SC is having spaces near the entrance converted over.
You can currently see where it appears the electrical has been trenched in from the street and spray paint marking how they need to jackhammer away the asphalt to route electrical conduit and put in curbing for the chargers.
Someone else check it and let us know if I'm correct on this one.
