I think the most beautiful drive that I've been on in years has to be in Southern Oregon on a state highway between Ashland and Klamath Falls. The road was deserted other than an occasional car. There were so many switchbacks and banked turns, the road was well maintained. It was just a beautiful and fun drive to make. I was very happy I took this route back to Salt Lake rather than going back down I5 to catch I80.
Here's a video of it. I'm obviously not pushing it as I'm taking a video from my cell phone and this also is obviously not my WRX that I'm driving either. (It's my old Tiburon.)
If anyone is lucky enough to ever be in this area I'd suggest taking care around some of the signs that post lower speeds for the turns, some of them are very tight and have very steep sides.
