<<The only reason I can think of that NFM is not yet doing this is they are waiting for a recession or depression to do that.>>
Tthis is the only reason that you can think of? And you claim to understand Buffett? Look at the way he allocates capital. Look at Sees Candies, a better operation than NFM. He has stated that he would love to expand Sees if they could do so in a way that meets his standards. You think that Buffett et. al. have not given the same consideration to the geographic expanision of NFM and not come up with the same conclusion? I do not understand why you go on for ages on the glories of Warren Buffett and then second quess him all the time. Especially when your second guessing is silly.
