That depends. In a RV-6A from the east I fly up to Leadville then WNW
over Turquoise Lake (I believe) then as Andrew mentioned. Just fly
over the mountains. No canyons to worry about.

What altitude do you fly, and what's the ceiling of your aircraft?

Also, do you use oxygen, and if so, at what altitude do you prefer to use it
(over and above FAR requirements)?

I'm about to try a Buena Vista - Turquoise Lake - Hagermann Pass - Ruedi
Reservoir route now, during the day (in real time). I didn't do very well
last night. This time I put lots of user waypoints in the GPS, just in case,
although I'm trying not to do anything that cannot be done with VORs alone.

MX,

Do you use oxygen when you "fly" that sim above 10000 ft? above 150000?
