Someone at Tesla loves Portland. This is the second SC that mostly benefits people from Portland (Detroit is the first).
If I lived in Portland, these would be the superchargers I used the least - I would be charging at home and so go right past them on a road trip.
However, since I live in East Oregon, I have felt the lack of a supercharger closer to Portland than 40 miles (Woodburn, so actually the wrong direction) a couple of times - it's 80 miles going back East from Portland. Which means that when I drive in and park at the airport, I have to charge enough at The Dalles to make it in to Portland, back again, and also counter the ~20 miles range/week I lose while car is sitting - so I don't dare be under 200 miles range heading into Portland. Now, I will be able to do the typical 20-minute charge in The Dalles, and have no issues with getting to a charger on my trip home!
And, getting in to central Oregon is always a fun challenge - so looking forward to the Burns charger! I only use SCs on a road trip, but without them, I couldn't!
