In tents now as we travel up the Khumba valley.  Feeling the altitude as we fight to stay warm and healthy. It has snowed in the afternoons and the temperatures have dropped to the single digits at night.  The food is getting repetitive – white bread with cheese, potatoes and carrots or coleslaw.  Playing cards with the Norwegians and music in the tent to pass the time.  Little headache at night and then a little nausea the next night.  Not sure why because breath wise I feel great.
