It took us 14 hours to get from Albany OR to Vancouver BC, A ~400mi drive.
The first 155mi took 10 hours, the I-5 between Albany and pretty much all the way up to Chehalis/Olympia was a mess.
Got home at 2am.
Still worth. Sight of a lifetime, I'll never forget it. Absolutely amazing. Anyone who calls 99% "good enough" is EXTREMELY missing out, it's literally a night and day difference.
