A binder can be a great way to collect all the little pieces of paper from one's travels. This can provide a great reference for future travels. I love to look back and see what things cost and what places you want to return to. I keep a zip-lock bag on my trip and at the end of the day drop the receipts and any notes to help jog my foggy bottom brain, so when I get home, I can arrange photos and snippets in an organized fashion.
