Someone mentioned handing down cast iron to the next generation. I have several cast iron skillets and dutch ovens. My oldest granddaughter has already inventoried them and laid claim to them "when I'm ready to let go of them".
I've always said that if a missile hit my house when they sifted through the ashes they would find the Griswold skillets and Pfaltzgraff dishes. That stuff is indestructible.
