I've lived in California's central valley close to thirty years. We are
right where the Sierra foothills start and on clear Winter days we can
always see the snow on the Yosemite area mountains from our house ( you can
see the top of Half Dome from here, they say, but I'm not convinced about
which top is which ). But, right now I can see snow down lower than I
ever remember seeing it ... not right at the house but certainly only a few
hundred feet higher.

Brrrr !
