The value of such a step extends beyond the mere task of shielding you from glacial shifts in the job market: if a major disaster suddenly cripples the local economy, there may be no more jobs for insurance claims adjusters or account executives, but carpentry or metalworking skills could be in high demand for the coming year or two. You can never predict it exactly, but the more you can do, the better you can cope with whatever adventures come your way.

Being from the south, we eat a lot of cornbread, so I would have to add cornmeal to this list. I think that cornbread would be an excellent option for a grid down situation. It’s very simple to make, cornmeal, and water, plus salt or any extra veggies you may have. I would also add dry pasta, and oil, for cooking and seasoning your cast iron. I may have missed this, but what about peroxide and alcohol? But you thought of a lot of things I never would have. Great list!

Not all of these hobbies can be turned into well-paying gigs unless you truly excel at them - but they are guaranteed to be challenging, meaningful, and fun. The Internet gives you ample opportunities to learn from others, compare notes, and get feedback on your work - all without prematurely subjecting yourself to the pressures of the commercial marketplace.
FoodSaver Jar Sealer: Already have a FoodSaver? If so, check out this jar sealer which can be used to vacuum seal your Mason jars. This is a great option for short to mid term storage of items such as beans, rice, sugar and salt. Store your jars in a cool, dark place and you are set with the added advantage of removing a small amount for current use without having to disrupt your large Mylar bag or bucket of food.
Buckets are great, but rats can chew through them. Store them where you think you can protect them from rodents. Also, plastic is somewhat air permeable, so mylar bag inserts are a really good idea. For basics, the LDS site is the best. You can get flour, wheat, beans, rice, sugar and some pasta already processed in #10 cans and boxed by the 6 can case. All my beds are on these case lot boxes so they take up zero extra room in my house. The prices are extremely reasonable since the church only covers its cost. I wouldn’t store anything in garbage cans just because the sheer weight of the thing will be prohibitive…unless you have a forklift lying around!
