Lying forecasters. Temps were supposed to be in the 20's, but I got minus 2F this Christmas AM, east of Carson Pass on 88 here in N CA. I had my WM Apache 15F bag. Luckily I had my down clothing to drape over me. Used my old MSR Whisperlite Int'l from '89, it sees little action these days with all my other stoves I can use.
