Flat?

Great day heading west.  We didn't exactly prove the world isn't flat today, as our drive was pretty darn flat.  Other than the hills from Asheville to Nashville, we saw a lot of horizon.  Tomorrow will be another ordeal after we get through the doldrums of Kansas, into the serenity of CO.  We look forward to making that big turn towards the Rockies, and promise to have some great pictures.  Bring on the altitude!
