The dumbest question is one that is never asked, right? Is the giant city a bigger bag than the city, or just a city with the giant hardware? Having a tough time finding measurements with names. Wish a seasoned bbag lover would compile a primer for newbies (hint, hint). I've found lots of color references and individual pics (thank you!), but no measurements to help me compare. I do not have much access to see these in real life. Many thanks!
