Dear Ed:

The lower the Barometer the lower the actual moisture content of the wood.  Also the lower the
number of air molecules per c.c. This makes it harder to control the humidity level.

Calgary can be -24 F one day and +10 the next. The have a name for this called a Shunook.  The
air flows are deflected by the mountain ranges.

What is necessary is a very beefed up Dampp-Chaser System on each piano. And someone to fill
them. And someone to change the wicks. And floor length covers.
