Ed,

I see a few problems with what you are saying.  If you are in Leadville at

9000 feet, you must be at the bottom of a mine shift.  Leadville is just a

little over 10,000.  Next, if it ever got to 95 degree there most of the 
locals would die (85 is hot), and I not sure an F-16 would get off the 
ground at 95 degrees on their 6,500 ft runway.

Sorry--could let it go.

You are right. I rotate at 65 no matter what the density altitude.
