Do you tend to come back from a trip (mine was to Washington State recently), and immediately begin to think of how you could perfect your packing, airport time etc., for the next trip?
It is interesting to listen to my daughter saying, "I really could have gotten by with even less clothing!" She has become a pro at packing light, and carrying her RS backpack on her back. I heard someone at the airport saying that they never saw such a tiny suitcases!
Thankfully we took only carry on this time because we had an 11 hour delay in Chicago.
