Eclipse chasing is also extremely compatible with FlyerTalk: Got to see the eclipse with perfect weather and looking at 12,880 air miles to get there and back home (and drove about 900 car miles).
I was practically on the centerline near Oregon/Idaho border area based on high chance of good weather, flying to/from SLC as this was a bit last moment, booked only 2 weeks before.
The traffic jams SLC-Oregon were less than I expected (none to get up there the day before, pretty bad, but not horrible, in a few spots driving back down to SLC, about doubling the driving time).
Agree with everyone about totality being totally worth even quite serious travel effort, partial is meh.
