Coast to Coast
As just mentioned, I grew up on car trips. For me, the idea of transcontinental travel is all mixed up with long, dusty drives.
I may sound like Rip van Winkle, but it will never cease to amaze me that I can wake up on one side of the continent (albeit quite early) and be on the other side before lunch.
I pondered this last night, as I watched the last light of a long day fade to orange, then black.
