Hi, nice thread here. I am almost finished with my build (a downtube 20", that folds similar to a dahon) and need a bag that will be bus, train and airline legal and be able to store one change of clothes and a small amount of miscellaneous items. It would ideally take the appearance of a large or "military" style backpack (minus the camoflage of course
). I can also only buy from ebay or local stores- any suggestions?
