For those who have never visited Fairbanks, there is a phenomena
observed at -15C and lower known as "square tire". The rubber in tires
of parked vehicles will become stiff and freeze into position, making
the vehicle impossible to move without destroying the tires. To the
best of my knowledge the ARSC does have conventional AC units, as
Fairbanks reaches +24C and higher in mid summer.





As someone who has lived in Saskatchewan all his life, I can tell you
that "square tire" does not usually involve destruction of the tire. If
your tire is slightly flat, it can certainly freeze with a flat side.
This makes driving interesting for a while, but the tire will thaw as it
is driven on.
