Round these parts our problem is the opposite.  If I waved a shirt
around outside for ten minutes right now, I could probably wring a
thimbleful of water out of it.  Both temperature and humidity are in the
90's.

In the winter, though, it can be quite dry.  We didn't get a humidifier,
but a) I always ground myself before handling hardware; b) one almost
never has to handle hardware in a well-burned in cluster room.  In fact,
weeks pass with no human even looking in at the nodes (except maybe by
e-camera).
