[Q]: Came across a YouTube video from July 2008, where a Russian border official on a night train from Ukraine checks a big logbook before stamping the passenger's passport.

What is the purpose of this, and is it still common practice?

[A]: What does Russian border control use big logbooks for?

[Q]: I am from Australia and planning to visit Canada and U.S this year. I got my ESTA approval but not sure about coming to U.S. twice in a month. I will be visiting NY from Toronto and then back to Toronto and then Vancouver. From there I am planning a trip to LV & LA. Will there be an issue as my second visit will be in a couple of weeks time again to U.S. Any help please as I am not sure about this, thanks.

[A]: Multiple entry in a month allowed under ESTA?

[Q]: I am storing a suitcase full of stuff at my college. At the storage site, I saw how luggage was stacked one on top of another. As some of the suitcases are probably very heavy, and as my suitcase will be stored there for a few months, I am wondering about the correct way to store the luggage to minimize the damage for the suitcases at the bottom of the pile. Should the cases be stacked sideways (as depicted in this image) or should they be stacked with the largest face pointing up (as depicted in this image)? Or would the two storage methods be equivalent? Finally how sturdy should a typical relatively new soft-case suitcase be?

[A]:
How should I be stacking luggage?
