Given a travel related situation, and given a specific question about the situation, summarize the question into a title

[EX Q]: When I was in Barcelona I saw many bike sharing stations in the city, belonging to a program called Bicing. Remembering how convenient it was to use the service in London, I decided to try and register. However their website was in Spanish/Catalan and the stations themselves didn't have a registration option, so I gave up. Reading up on Bicing later on I've found the following paragraph on Wiki:


  The Bicing member cards are only sent to addresses in Catalonia in an attempt to prevent tourists from using the system.


Is this still true as of 2016? If so, is it possible to register and send a Bicing card to a friend's/hotel's address?

The official website also mentions an "In person" ("De manera presencial") registration option. Is it possible for a tourist to use that instead?

[EX A]: How can a tourist register for the Bicing bicycle sharing in Barcelona?

[EX Q]: I am considering taking a trip to England this summer to check out a university. For money (and experience) purposes, I would prefer to travel alone. My plan is to fly on Primera Air from BOS to STN. According to Primera's site, I should be fine flying with them alone as a 17 year-old, but will entering the UK pose an issue? All I've found is a page on gov.uk that only seems to apply if you are applying for a visa, not if you are entering visa-free (as I would be from the US).

I do have friends in the UK that I would be staying with.

[EX A]: Can a minor (17 years old) travel from the US to the UK unaccompanied?

[EX Q]: Do gas station in small towns or rural areas in Northern Ireland and the Republic of Ireland accept credit cards and debit cards for payment?
