Congratulations! I am glad to hear that your IPOD worked. I read that you aren't supposed to use it over 10,000 feet. I've been thinking of using a Sansa Clip (flash MP3 instead).
Do you really think it helped to stay 2 days in Portal? My husband and I plan to go up on Labor Day, and camp at Portal, camp at Outpost, camp at Trail and then summit (hopefully)!
