Detailed Instructions: Given a travel related situation, and given a specific question about the situation, summarize the question into a title
See one example below:
Problem: The green carriage is of course first class. This would be our first preference with our 5 month old baby in lap, because of the presumably larger toilets for changing and whatnot.  However, the baby being a Western white baby... will occasionally babble, screech or cry uncontrollably for a little while.

Speaking in terms of Japanese culture, should we avoid Green class tickets if we are taking aboard a potentially disruptive baby?

Solution: Japanese train etiquette: Is it acceptable to take a baby in the Shinkansen Green Car?
Explanation: A person gives a detailed description about a situation where they would prefer to travel on the Shinkansen Green Car but is doubtful if doing that would be against the Japanese train etiquette since they will be traveling with a baby. The question is summarized as Japanese train etiquette: Is it acceptable to take a baby in the Shinkansen Green Car? for easy indexing the next time someone searches for a similar phrase

Problem: In a while I will be traveling to Norway for a hiking trip. In between getting from the Oslo Gardermoen airport to Finse, I'll have to get gas cans with a that are UNEF 7/16" threaded, which means they look like this: 



Any tips on where to get these? preferably at shops near the airport.

I already found Oslo sportslager, who sell these for sure: http://www.oslosportslager.no/produkt/beaver-power-gas-450-gassboks-25070.aspx

But in case they're out of it, it would be nice to have a backup plan :)

Solution:
Locating outdoor / hiking shops which sell gas cans in Oslo?
