Friday has us driving down from the peak of Bryce Canyon at 9100' to Laughlin Nevada at 400'. I have pretty bad congestion, even with many decongestants. And our descent is not gentle as we soar down the I-15 from Utah across Arizona, and into the bottom triangle of Nevada.Ears. Oh, my ears! The road is a roller coaster of a few thousand feet in a few dozen minutes, up and down and up and down. Pretty, though.
