I'm in the Sunday School presidency in my ward, and we're toying with the idea of having food storage classes in Sunday School. It would be a combination cooking demonstration/strategizing/how to/etc. It would be a limited class size Sunday School class, but we could take videos for showing others in the ward.
Maybe even, with the limited class size, we could do more individual counseling with people how they can get their storage started or how they can improve it. The Sunday School president and I are both into preparedness so we have a lot of info that we could pass on.
If any of you have done anything similar in the ward I'd like to hear. I want to pitch the idea to our Bishop.
