<VV> Descending a mountain

Well, the weird thing here is...  for every 1,000 feet of altitude, the temp 
drops 3F degrees.  So, as you go up the mountain the engine will be working 
harder (than it will later - downhill) and the ambient temp will be 
dropping.  So, depending upon how steep a slope you just climbed AND the 
altitude you are at AND you could probably throw in the lower barometric 
pressure to the equation (less air to mix with the gas), it might be wise to 
find a wide spot [Overlook?] and give yourself and your pretty pickup truck 
a 15 minute break before proceeding on.

Later, JR
