What to pack or what not to pack,
that is always the question. There are often mental calculations involved around what you will be doing, and where you will be going. The shoes in my opinion are always the trickiest part sometimes due to whether conditions, and other times due to the geography and road conditions of the trip, so I always pack a heel and a more semi-casual flat just in case for an evening out. I like to cover all of my bases.
I like the idea of the list, keeping one in your closet so that you don't have to think about what to pack in a pinch, because no matter how often you travel it always proves to be a mental challenge.
I also like the idea of being prepared and organized enough to be travelling with your own suitcase hooch. Although times have changed and finding a drink somewhere somehow is no longer a challenge, one never knows at what hour one will need a good stiff beverage.
That being said, may your summer journey to your destination prove to be as predictable as this list and may the rest of your vacation be agenda free. -tM
