Hey TAK - that's kinda my thinking, and right now it is a lot easier to "try out" a particular set-up in a particular temp combo on my patio than in the woods.
Day 1: Wednesday
My camp security was a bit lax and we got attacked by some banditos...
I think he was quoting Hamlet here.
My final set up before the storm. Quite comfy, actually.
Weather for the night. Lots of rain, never got below 47F. My tarp set up kept me dry, my quilt was WAY to warm ... [URL=http://s257.photobucket.com/user/jkartzinel/media/IMG_0568.PNG-1_1.png.html]
Day 2: Thursday
Sleepy camping buddy.
Coffee. The camping necessity.
Weather gonna be a bitty chillier. got down to 34, nice brisk gusts.
Day 3: Friday
OMG It snowed! [URL=http://s257.photobucket.com/user/jkartzinel/media/IMG_0606.JPG_1.jpeg.html]
Snug as a bug in a rug. A little tight rug, that has a few spots where cold air comes in. [URL=http://s257.photobucket.com/user/jkartzinel/media/IMG_0607.JPG_1.jpeg.html]
Tonight it'll be getting down into the high 20s, I might do this one more night, but I think that 32F is a pretty realistic limit for this bag in this set up, for comfort. I think if I had a bigger size (or I was a smaller person) I could get the 20F rating out of it, and I know I could get down to 20 in this and just have a fitful sleep. But it was a good and fun experiment. I'm more comfortable with my bag, pad, tarp, and stove now, and it was a good experience.
Hopefully next time will be in the woods... It is really hard to get out of your toasty bag, go into your toasty house in the middle of the night to pee, and then go BACK outside .... Just sayin'.
