lowering the Humidity in Seattle is like getting the Sand out of a desert..

I'm using an Oil filled electric radiator (portable) to heat one room in my apartment right now.

costs too much to heat anything More.

Partition off the work area so You dont have to pour out the quantity of heat
to bring both car's worth of space up.

NOAA says : Patchy freezing fog. Mostly cloudy, with a low around 32. Light east wind...
So frost on road and MUP where the shadows keep them in the shade.

high will not get far from 40.
