Kathi, I had the same thought the first time I went skiing after my ACL surgery, particularly with the pants since they had to cut them open in the medical center (my fleece pants, but I liked them so I sewed them back up). I realized I was being fearful and that was no good, so to conquer the fear I wore all the stuff and its been fine. Have a great day! Jeez, I'm jealous thinking of you up there while I'm sitting here trapped in my window-less office.
The best part about going up hills is riding back down!
