This past weekend I posted a picture of my carry-on bag in it's partially packed state for my trip to the UK and Europe. I included this caption:
Packing for my 13 day excursion to London, Paris, Barcelona, and Rome. I'm not checking any bags, this is my carry-in w/ 11 outfits and a jacket in it. I'll have a small personal bag that attaches to this one, and it has everything else I'll need, including a book.
