Thanks for the replies. I enjoyed the Man in the Blue Shirt thread.
My pack list is fairly well tested and almost everything in my closet was purchased with an eye toward travel.
Including what I wear on the plane, I generally always pack two pairs of pants (usually golf pants because they look nice and dry fast), something to swim in (usually hybrid shorts), two button up shirts and three t-shirts (all non-cotton), one pair of walking shoes that can get rained on, one pair of flip flops, a warm layer (again non-cotton), a rain shell, three pairs underwear and socks (all non-cotton, socks are all identical so I can lose two and still have matching pairs), a belt, a knit cap (as much for bad hair days as warmth), light sweat pants and hoodie (again non-cotton, for lounging, sleeping and laundry day).
I pack two ziplock bags of toiletry: a bigger one for all the dry stuff and a quart size with the wet stuff. I pack a largish synthetic chamois to use to wring laundry (if I do it in my room) or as a travel towel when needed.
I've reduced paper to nothing. I bring a kindle version Rick Steve's guide in my phone. Itinerary is on a spreadsheet saved to my phone. Copies are photos saved in my gallery.
Electronics are now all in my phone: Phone, GPS, Alarm, Camera, etc. I bring (usually) two small chargers and adapters plus a couple cords (in case I leave something in a room) plus a plug-in charger for the car.
I weigh my bag and decide what I can add, an extra t-shirt, underwear, socks (or take away). Lately the splurge item I end up adding is a Michelin Green Guide (too bad they don't offer kindle versions). It all goes in a bag small enough to carry on Frontier Airlines or Ryanair (used on both airlines). If I weigh in at ten lbs. I feel pretty good. At 12 lbs. I feel like I need to ditch something (and do).
