That looks like a nice record of some fun times! And memories barely take up any space at all.

I've been on a major cleaning/reduction kick lately, too. In fact I just got rid of two huge file cabinets after scanning in a lifetime's worth of handwritten journals and stories. And my library is down to just half a bookshelf. It's so liberating to consider that everything I care about now fits in the back of a Toyota Prius.
