Imagine that you are a bush pilot in Africa. You fly in some critical medical supplies, enjoy a quick lunch at the hospital and are eager to get to your next appointment. It's a stifling 100 degrees in the shade.
You return to your plane to find that the only bit of shade within a mile has become very popular, in your absence...
You start calculating the distance to the plane door....
Whad'ya say? Feeling lucky today???
In future I will have further pictures and information regarding travel.
