The other day, I stumbed across The Burning House. The general idea is that people photograph their most precious possessions- the things they would be sure to save if their house was on fire. I loved looking over the things people chose.
I especially love that this one has a Le Creuset dutch oven in it, because I have the same one, and I certainly couldn't bear to part with mine. I'd definitely also want my old diaries (I've been keeping them since I was 11) and my grandmother's pearls.
