Very nice Targus backpack/messenger bag that can hold a large laptop and much more. More secret compartments than I can count (cell phone, water bottle, pens, documents, etc.). You can use it as a backpack or hide away the backpack straps and attach the padded shoulder strap to carry it as a messenger bag.
Several years old but used only a couple of times for job interviews. Never traveled with it, but it would hold up to some pretty serious abuse.
Pickup today or tomorrow (4/18 or 4/19) is preferred.
