Yeah the Tumwater location was so odd, that I think Olympia will get one too. Either on the west side to service US101 or more likely in or near Lacey to service I-5. There definitely needs to eventually be a supercharger in south Tacoma or Lacey or some place in between. Right now there is still nothing along I-5 between Lynnwood and Tumwater with the exception of a pay garage in downtown Seattle (no one road tripping wants to stop there to plug in). I get that Auburn is not that much of a diversion but it's still kinda crazy given how many Teslas there are around here now.
FWIW, I do think the Longview pin will eventually go away. It would be super weird to have superchargers in both Kelso and Longview.
Drove through Longview from the Oregon Coast this morning. Supercharger does not show up on map on the car nor does it show up in the app under charging. Also tried searching for Longview supercharger in the car with no results. Looked it up on the Tesla website to find the actual address and navigated there. (207 Three Rivers Dr, Kelso, WA 98626)
