OK, so this is kind of similar to the adventure box – which we’ve moved the adventures to their own box now. But on our random journeys we tend to pick up detritus. Whether it’s a map, a cool rock, brochures, random “toys” from skeevy truck stop vending machines (Creepy, yet hilarious to read the instructions). You know, stuff you have absolutely no use for, but that you acquire and want to keep.
I can’t remember where I saw this, but I used photo boxes to hold this stuff.
