I loved this story. Especially poignant was when he said he realized how postcards didn't make him remember his London, his Paris, or his Istanbul. Sometimes amidst all this gear-hunting, it is nice to be reminded of the why, and not the what. And it is nice to be reminded how lucky we are that we are able to keep mementos we can go back to -- even now I find extreme joy when going back to pictures of my kids just a few years ago -- I can barely remember that they were once that small. Especially delightful is running into a photograph of a moment you already competely forgot, but there it is in your photo.
