This post and your other about taking steps to keep "healthy" on the trail at altitude cause me to respond.

first and foremost: on a ttips forum "jeremiah johnson" made my top 5 movies of all time.......great pick: it is one of the many many things my wife has introduced to me and one of the great things we have shared over the past 28 years..........

I will start a top 5 movies thread here..........on the OT

Sounds like your friends certainly know your gear and I cannot blame them for claiming the items or for you to want to stay one step ahead of them :-)

Finally, in your last thread about altitude prevention. I am not an expert on altitude sickness but most experts only recommend preventive therapy for AMS/HAPE/HACE if you have had problems previously. Those over the counter supplements are probably not all that helpful, beyond the placebo affect. Most people suggest Diamox or Nifedipine as first line treatment/prophylaxis and to high tail it to lower ground. NO or nitric oxide is very controversial in medical treatments as a FYI.........
