"I would also add a small, flat wrecking bar to your pack. It will make it easier to get into the vending machine at work"

DO NOT make a dry run to see if it works!

Back to the socks... I didn't see that you had four pair, that should be enough.

Pack whatever you think you'll need. You can always go through your stuff after the event (such as when you're resting, or waiting for daylight to start) and leave behind what you aren't likely to need. Leave it in an obvious place, someone else might have a use for it.
