Oxygen Please

The town of Breckenridge sits at 9,600 feet elevation.  We are staying and skiing at Peak 9 which sits at 10,500 at it's base,  rises to 13,000 feet at the summit.  We learned from our last visit that breathing is not easy until you get acclimated, which is usually about the time we leave town.  So we got smart and accessed the oxygen service.  We all used it, Daddy slept with it on to provide better rest at this altitude. The top picture is after a day of skiing - I might look like I'm suffering but it's a good suffering.  Can't wait to head out to the slopes tomorrow.
