you can weave a couple of baskets in an hour or so, line them with chunks of tarp and duct tape and have the "buckets" that you'll need to refine workable pottery clay out of shoreline mud. In one day, you can have a couple of 1-gallon pots (with lids) plus 50 or more baked- clay balls for use as "ammo" for the slingbow. That's one of the main reasons to take the slingbow instead of a regular bow. You dont lose or damage arrows or waster hours looking for them, when all you had a shot at was a chipmunk,small bird, etc. When you're holed up for the winter, pebbles or ice balls and the slingbow will entertain you, too. You can also make a pottery sieve-ladle. Add 5 ft of wooden handle to it and you can remove ice shards from your fishing holes and net-slits for ice-fishing, which delays how quickly new ice forms on the surface of the water. You need to avoid getting wet as you do this, of course. The 10 item limit really shows how little people know. You DO have to move a bushel or two of shoreline mud to your shelter before it freezes, but that's just the work of an hour or so. The hot rocks under the raise bed, your body heat and the Siberian fire lay, projecting its heat thru the clear vertical side of the Kochanski supershelter can add 80F degrees of warmth to the sun-warmed shelter, so you CAN work pottery, regardless of it being 20F degrees outside of the shelter. With such pots, you only have to cook or boil water once per day. That's a huge savings of time during the precisous 40 days or so that you have before the lake freezes over. It takes a week to get set up to net fish much at all, and at least another week to get into full production. That leaves 3 weeks in which you need to catch at least 300 lbs of fish if you want to last 100 days without catchng a big animal and if you need to go 200 days, you'll need to catch 700 lbs of fish. You'll only be averaging a few lbs of fish per day thru the ice, in spite of having lots of hooks, baited nets, etc. So you've got to lay in a big supply of frozen fish. before the lake freezes over.
