Every year about this time I go to the mountains with a friend. The cabin is at about 6200 feet elevation. I frequently feel yucky the first day while I accomodate to the altitude. This year I am 47lbs lighter, and I had no trouble at all. I could walk and breathe at the same time. We went out to eat and I didn't feel sick. I am so pleased!
We also went to the local grocery store and they had Satsuma Mandarin oranges, so I came home with a whole passel of oranges. Yum.
