Martin,

Excellent points. And as luck would have it, I actually happen to have
a small aluminum bottle that I can use.

In addition to the electric socks that someone else suggested, a
backup O2 bottle is a wise idea. Mtn High used to sell them for about
$100. Buying or borrowing a Nonin or other oxymeter would also be a
good idea. How else do you know your O2 is working properly? Maybe the
cost could be shared with some others.

After I went to 27,300 in wave at Minden some years back, I came back
to my club and told people about my great flight -- in short sleeves
no less -- it was July and blue and sunny. Almost to a man, they
responded "What did you do for O2 backup? Did you have a bail out
bottle?" I had to respond, "Hmmm... hadn't thought of that. Everyone
just said 'Wave's up. Get in your ships.'"

But, as I checked into useful consciousness times at those altitudes,
I realized they were right and bought the Mtn High system. Since I
have it, I keep it in the ship whenever I might need O2. Small, light
weight, and a nice redundancy.

PS to the story: The next Spring the club was planning a wave camp at
Minden and I asked "What are you doing for O2 backup?" The answer,
again to a man, "Well, we ought to have backups, but we don't, so
we'll fly anyway."

With local cloudbase rarely over 7k, I'm going to have to go somewhere
else for Diamond Altitude. I figure I might as well freeze someone
else's gelcoat so I'm looking for a commercial operation, preferably
someplace close to an airport served by Southwest Airlines.

Thanks for the advice and note that my "reply to" has a duplication in
the domain.
