This looks like it could be the next big route push for Superchargers. Take look at the Google Maps route that I overlaid with a screen capture of Tesla's 2015 map: The route looks like: The Dalles, OR - Open Pendleton, OR Baker City, OR Boise, ID Twin Falls, ID Tremonton, UT Salt Lake City, UT - Open There are already strong rumors of Pendleton and Tremonton. That just leaves Baker City, Boise, and Twin Falls in between. Remember these locations could also be a nearby town. This map also implies Richland, WA being added in 2015 to connect the Portland, OR area to the I-90 route, and a Supercharger in Bend, OR.
