I went to the local Macy's (insert any other place with a "fragrance" section) to get some more of my favorite cologne and shaving goods. While shopping, I was handed a couple of those "sample" spray vials (which are good for about a week with 2x puffs per day). I asked if they had X, Y or Z (colognes I like) and they proffered up more samples.
My cologne is easily accommodated in my 311 bag in a very small format for our upcoming 3 week adventure. And I get to try new smells (which actually are a very strong connection to a memory). You get the point. :-)
