Made in the shade

Imagine that you are a bush pilot in Africa. You fly-in some critical medical supplies and enjoy a quick lunch at the hospital. You 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 piece of shade around has become very popular, in your absence... You start calculating the distance to the plane door.... Whad'ya say? Feeling lucky today?
