Rob,
I took my 360 up to FL210 last year = over the high=20 desert of southern California to ops check my new mountain high oxygen=20 system.  Performance was very good and I didn't think my controls = were=20 mushy.  I could have gone higher but was only using the canula = where I=20 should have had a mask!  As you pointed out, wind and weather would = be=20 other significant factors.

15 years ago, just before I started my not-yet-finished = Lancair=20 360, I climbed to the top of Mt McKinley in Alaska (Denali - 20,320 = feet=20 MSL).  I don't remember the summit day all that well because I = was=20 focusing on getting to the top (my friends say I was just focusing on=20 breathing, and they may be right) and a whiteout happened just before = the=20 summit, so on the down-climb I could only see about 150 feet.  I = don't=20 even have any pictures of that day, althouh I do have some good = pictures of=20 the lower elevations.

I just finished reading a new book about = the 1967=20 climbing disaster atop Denali and it made me realize that I really = want to be=20 able to remember what it looks like up there.  I thought briefly = about=20 climbing it again, but fortunately sanity returned in short = order.  Then=20 I said "Aha!  I'll just fly my Lancair up there and take a = look!" =20 (Although, maybe hypnotism would be the better = choice...)
