Replying to a message of mark lewis to Bob Ackley:

 BA>> Yes.  The German Army discovered that during WWII.  Of course, it

 ml> not only that, but there is a reason why those in the extremely cold

 ml> concerning drilling operations in those extremely cold climates...

In this area during the winter many if not most truckers leave their trucks idling
at truck stops rather than shut them down.  I noticed that several years ago, I
don't know if they do it in the summer, too (to run the cab a/c while they're
sleeping ).
