To keep warm, climb a mountain.

You might think we are crazy, but we've noticed that the temperature usually rises an average of 8 degrees as we drive up our mountain.

So a few days ago, we took a picture of the thermometer in the car, 
as we headed down the mountain from 9,370 feet.

Then just west of the city of Blanca, at 7,700 feet, here is what we had:

That's a 24 degree drop in just over 30 minutes, as we drove about 1,700 feet down the mountain.

We first heard something like this while in Denali National Park. Aparently, in the 1920's the first ranger had been given a cabin near the river which was to be his home.  Being a "local", he knew his stuff.  So, he abandoned that and personally built a new cabin at the top of the mountain....where now you see the hotels used by the cruise ship companies for their land tours to the park. The temp was 20 to 40 degrees higher up there.

If there's a lesson here......
maybe you should always take extra clothing when you go on a car ride,
no matter how mild the weather might seem when you depart,
'cause you never know what you're going to get.
