I'm digging this thread... I've camped on ...
This winter, I'm planning on doing it in January and Febuary, on purpose. The logic is, if you can survive dead of winter with your kit, the rest of the year will be a picnic with a backpack on.
For me in the Sierras, I worry more about transitional seasons where I get rain/snow/thaw/freeze than just cold. Way easier for me to stay dry & warm when it's constantly below freezing and without rain.
