Planning to take a journey that was unplanned does not mean that no planning occurred. The obvious example? We purchased tickets to and from Amsterdam. We planned to be gone for a definitive period of time. We planned to travel by train. What was “unplanned” was any semblance of an itinerary after day 1.
Though we had no schedule or to-do list we did have to prepare. We had to pack clothes for the journey. These clothes would need to provide flexibility in a variety of social and climactic settings, would be generally consistent with the local styles, allow a certain number of days’ continuous travel, and had to fit in a carry on sized roller bag and a rucksack. Each person has to be able to schlep their stuff up and down stairs and passageways if required.
You start by selecting your laundry interval. That is the number of days you can go without having to hand wash or launder a particular article. I won’t delve too far into the question of “how many times can I wear this T-shirt before it’s dirty?” For purposes of this discussion we will assume you can wear something one and half times. A wearing is a full day. So if I wore a shirt all day Tuesday, I could wear it Wednesday morning during the early walk and activities prior to showering. Thus a day and a half. Smoky rooms or rain may abbreviate the wearing period.
The only exception to this rule is underwear. Once is it. No inside out, No Commando unless you are deployed in an active war environment. Maybe can be stretched to include the early next day walk. Butt no further.
Our laundry interval was seven days. Guess what is happening on Saturday evening before we paint the town red? You got it. Laundry. I have worn all of the pants and shorts in my bag, although each is not to the full 1 and half day limit. Somehow I still seem to have plenty of clean shirts. Four I think. This seems to happen every time I travel. I have started to think that maybe all the extra baggage you end up with is just your own shirt.
