I've been using the ziplock bags for years. They work great. One year we went to Jamiaca back when they went through your luggage at the airport down there in front of everyone. They just lined up your bags on these wooden benches and started going through all the suitcases while everyone is standing around watching. Well, everything I had packed was in ziplocks so they just pulled out the bags and looked through the suitcase and put the bags back in - neat and tidy and nobody sees too much. The couple next to us, meanwhile, have all of the their unmentionables strewn all over the bench for everyone to see, some of them fall on floor (Yuk!). She was so embarrassed. She looked over at us and said that she had never thought of packing with ziplocks but after having been through that experience she was never packing without them again. Just another reason to use them.
