Rick, my regular bag is only good to -5C so I need the overbag-it doesn't weigh much. The two pads are a Thermo-rest, plus a Ridgerest that weighs almost nothing, so no real savings there. I use the blue pads outside the tent to sit on while cooking or just sitting around.
I could ditch the extra stove, but I carry it when dayhiking. I do have plenty of cold food-energy bars and whatnot, but like a hot drink.
I've got this tiny sled, not one of the big toboggans or even a Paris Expedition, so that needs to change.
If I had the money, I'd get a little BD tent that weighs about 4 lbs, but that is not feasible right now.
No snowshoes, just skis. For CA, and where I go, in particular, skis work better I think.
I could ditch some of my other stuff, but given the weather forecast, maybe not such a hot idea. Most of my trip will be on a snow covered road, so the sled actually tracks and glides fairly easily. With two people, some of the load would be split, but alone, it's all me carting it in.
Don't get me started, you know how I get.
