For Y2K, ( dead giveaway on age), we used the five gallon bucket that could be opened with a tool of some sort. After doing huge buckets of rice and beans, it dawned out us that the five gallon was a smarter more. We added mylar bags of hard winter wheat, summer wheat, popcorn, hard candy, rice and beans. Five year later, and under the light of our still functioning grid, all was well. Everything tasted fine. This gave us a good deal of variety in each bucket. At that time, we were hopeful that kids and grandkids could magically appear on our doorstep, from all over the country. Only a small scattering was nearby. I wish we were as really now, because we had everything one would need back then... And I mean everything....
