Just read through this entire thread, very interesting.
Regarding using sawdust as filler, if I had access I would much prefer using shredded beet pulp as filler over sawdust. Used to feed it to horses a lot (soaked first).
What I would really like is a whole house generator, honestly. And enough fuel to run it until the power returns. I do a lot of freezing, need to keep the freezers going. I really ought to get Mom to teach me to pressure can and do more of that, maybe this year.
We have a small garden this year, I'll freeze excess. And I breed my chickens, so I always have chicken available. That's about it so far.
The weather here in Illinois is seriously hurting farmers this year, it's awful. Prepare for not only feed, but meat prices to rise since it's going to cost more to feed livestock. We don't only grow corn, we grow soybeans, oats, wheat, rye, etc here too.
