I have to give these three guys I went witha LOT of credit--they really took care of me, waited on me (when I was hunched over on the trail, trying to breathe and looking for my lungs which I was sure had fallen out of my chest a ways back),
I know that exact feeling. I felt I was in great shape when I went. But my lungs just could not handle the altitude well. Hunched over gasping if I didn't take it slow and easy. It's a very strange feeling for me knowing my muscles were not giving out, it was my lungs. We made camp on top of the mountain though at 11,000 feet. Morning hunts were a little easier for us.
