On my way from Spokane, WA, to Portland, OR, for a field trip with my students. I usually drive, but I figured out that flying actually costs the university less (because they reimburse you per mile when you drive), and it shaves about 2 hours off the trip. Not that I don't enjoy the drive - it's beautiful, especially through the Columbia River Gorge. But flying certainly gives you a different point of view, and it also allows for the obligatory time-killing in-flight sketch. That's Mt. Hood out the window to the left, as we were making our descent.
