LDS=The Church of Jesus Christ of the Latter-Day Saints, shortened to LDS, aka the Mormon Church. In many cities the church has "canneries," where members (and others) can come to seal food (and maybe other goodies) into #10 cans. Each church member is supposed to have a full years food supply on hand. Hence the old joke about, when the food riots hit, making money selling maps of where all the church members live...
