Awesome, thanks for the info. We did the Sisters route last year on the way home to North Vancouver from Bend. Beautiful drive up to about Detroit Lake, then not so much. We did the Mt Hood route on the way to Bend and that was a gorgeous drive. I was amazed at how when you climbed out of the Hood area you were all of a sudden in desert. I'm still amazed at how quickly the topography changed. One minute you're in the middle of massive pine trees and the next you're staring at sand, rocks and flat straight stretches that went on for miles and miles.
