Amen. I think you learn more about a city/country by spending a hour or two in a laundromat than a day in a museum.
I try to travel light, particularly when I'm on a bike but even when I'm not. Did a month in Europe last year with one 23 liter (~ book bag size) backpack/pannier and a bike, and a month in Asia this year with one carry-on size duffle (no bike, but lots of trains
. One dress shirt and one pair of khakis, a pair of shorts or jeans, and a few technical (i.e. quick dry) t-shirts, including a black one and a long sleeved one. If I'm on a bike, I skip the khakis and dress shirt and go with jeans and bike shorts. Part of the trick is to not pack all the "what if" stuff. There are stores everywhere -- every so often I have to buy something, which usually turns into a daily use souvenir when I get home.
Item 3 below, back in the 1970's -- boarding #7 at LaCrosse, had bicycle, totally worn out after riding from Chicago.
No box required. (officially,at the time, had to box your bike, but -- the crew just threw my bike in the bag car) No fee. No bike racks in bag car. No worries.
As for carry-ons - yeah - some folks try to carry on the kitchen sink and more - not just on Amtrak, airlines also.
Oh. and airlines -- back in the 70's same trip, checked bare bike to Chicago. And carried on a bag of bike tools - screwdrivers, wrenches, spare parts -- total carry-on less than 2 cubic ft -and 15 pounds - but lots of metal
Inspector checker looked, I said "bike tools" -- no problem.
What I've learned in laundromats has been
1: in manhattan -- wait your turn, not so long, very polite people.
2. in Tokyo -- cheap business hotel had 2 washer-dryers for a 10-story hotel. -- reserved for 2 am - jet-lag helped. very polite people - wandered Tokyo in wee hours waiting for dryer, never felt safer in a big city after midnight in my life.
3 biking across Wisconsin a few decades ago -- had 2-day change of clothing. got clean at some hicktown full of Brewers fans , caught the EB at LSE and checked bike no probs -bike rules informal back then
4 in Albuquerque staying at cheap motel 4 years back -- at the nearest laundromat on route 66 - few customers midday, but bought a couple green chile burros from someone off the street for a dollar each -- real good.
