Thank you, one and all, for your comments. I am leaning more towards the canned and rotating stock vs the FD cans for in-place situations. I am sure there is a place for the FD, I just have to figure it out. Having the two options for dealing hunger cannot be a bad thing. It will come down to how much do I need for how long?
