PROBLEM: Recently, I was cruising on the Danube river from Bratislava to Vienna and we were encountering these small green rocket-shaped objects floating in the water roughly after each kilometer. They were not staying still but also sailing in the same direction as our boat but slower.

What are these UFOs (Unidentified Floating Objects)?




SOLUTION: What are these small green rocket-shaped objects floating in the Danube?

PROBLEM: I'm taking a short vacation in northern Taiwan around January 1 and I want to travel about 90 minutes away from Taipei the weekend before New Years. I've had some difficulty reserving the train tickets I want online for the express trains. I can reserve some trains on the days I'm traveling, just not the exact ones that I want.

I've also observed that hotels are all nearly booked up (I have already made reservations).

However, I understand that I can always get on a local train without a reservation. How busy are the local trains from Taipei to Yilan and back the weekend before New Years? I can stand for 1-2 hours if I have to; I will have a large backpack as luggage, though. Thanks.


SOLUTION: What is it like using Taiwan's local trains around New Years?

PROBLEM: The H1B visa is valid starting from the 21st of September. If I take a multistop flight from New Zealand that passes through Honolulu and LAX on its way to Seattle, will my visa validity be checked at Seattle, or when I enter the US (Honolulu), or will it vary?

The stops at Honolulu and LAX are on the 20th of September local time whereas the arrival in Seattle is on the morning of the 21st.

I was just wondering because I would like to arrive as early as possible.


SOLUTION:
When is visa validity checked when entering US on a multistop flight?
