Working weekend, and a question

Heading out shortly to a writers conference in Utah, with a stopover in Colorado to pick up my sweetie. I'm looking forward to hopefully meeting some great new writers, getting to spend time with some colleagues, and of course, being with my bear. We've got an extra day to ourselves which we're hoping to take advantage of with some hiking.

But on to the question: I've been streamlining my office recently, and packing up some knickknacks for the eventual move to Denver, and recognizing that I do, in fact, have an AWFUL lot of knickknacks. Is it time to prune them down? And if so, what do I do with them? Throw them out, pass them to others, sell 'em on ebay? I'm keeping lots of things, but then there's stuff like this: What do I do with that?
