Last week we asked for backpack carry-on recommendations.  See the post here: https://brigada.org/2023/04/23_38140/comment-page-1#comment-426900.  We received several recommendations: Mother Lode Junior from EBags (www.ebags.com),  GREGORY Day and a Half pack, and REI convertible backpack.  Do you have a favorite you would like to mention?  How about carry-on luggage?  What’s the one thing you would recommend to a friend when packing for an international trip?  Thank you!
