It was 18 here in the Northern Nevada High Desert this morning. This is pretty typical for us. The big difference is that our humidity stay's around 12-15% and being so dry we don't feel the cold as bad as you folks do. What we do have problems with when the humidity is this low is static electricity. If you come to visit don't bring your polyester, cotton is what you want or you'll get zapped a lot and it aint fun. Pulling back the covers at night is a regular lightening show.
