I wish I had keep all my old copies of the Limbo newsletter.  Many moons ago
there was an article in it about a fellow in Alaska who ran a fleet of
Vanagons in some manner of a service business.  He claimed that whenever it gets cold
enough, they all leak only to stop once it warms.  He paid little mind to the
leakage.  This was from a guy who lived where cars are left idling overnight.
