Carrying a small notebook is quite useful, I can't stress this enough. Field Notes makes awesome memo books; I carry one on me every where I go. After all, you never know when a great idea will come to you. I even carry their pens, which are sleek and perform well. These "National Crop" memo books are especially cool, but they're a limited time offer. Check out the link to find out more about them. I tip my hat to Field Notes for making another quality product!
