California 395 north to Oregon in early February

If you have never taken that road in the winter, do it (unless it is blizzarding). Incredibly beautiful. Take your time -- stop in Bishop, and Mammoth, and Lee Vining. If you are into snow-shoeing (and who isn't??), there is an infinite amount of great terrain to explore.

The picture in my signature was taken just north of Lee Vining in the fall. In the winter, it is even better.
