One thing you probably know about, but won't fully appreciate until
you've been there, is the cold. After a climb to 27,000 feet I
couldn't feel my feet. Pretty much the same thing happened after my 3
hour XC flight, although I never went above 15,000 feet. I had on silk
socks, 2 pairs of wool socks, and moon boots made of thick closed cell
foam. Bring lots and lots of warm stuff, but you will definitely be
very cold!

Thanks again. All helpful. I'm in fairly good shape and don't smoke,
but 59 years old living at 800 feet I will probably want O2 in my
hotel room.

It would be great if I luck out and get a wave day, or even enough
ridge lift to stay up long enough to freeze.

I sometimes use those disposable packets that you put in your boots.
They keep some of your toes warm for a while. I also hear that fresh
socks right before you launch helps a lot.

SSA magazine just came out with a great article on wave flying
