Coming down for breakfast in Salida, I chose to stare through the stair treads. Vertigo is not one of my weaknesses.But we had a fitful sleep on our first night at any altitude. The only visible clock was on the microwave. I looked at it at 14:20, at 16:40, and at 19:55. Um, I knew that wasn't right! When I finally saw more light coming in around the room darkening shades I reached for Karen’s red flashlight and checked her clock. It was 6:45. Our alarm was set for 7:40, so we figured, close enough. This is MDT, so our bodies think the alarm should have gone off anyway.
