This post was stimulated by Abby's current trip to Italy. She invested much time in planning & packing. She bought a large backpack for her suitcase so they could move from city to city in Italia with greater ease. Low and behold, AA lost her bag / backpack. She is 8 days into the trip and she still doesn't have it. Her first day in Florence was very stressful because she wanted to be out exploring the city instead of out shopping for underwear. She did finally just go out and buy what she needed (and AA will be getting that bill.) But I know she wishes she had at least some of the things she packed.
