But I thought it is generally acceptable for cities with 'city' in their name to just take their first name on this site, no matter what they are called. I am so used to it I didn't think to type Oklahoma City. This reminds me of the time when Mexico City did not get accepted on the World Capitals quiz unless you typed its full name, while Guatemala and Kuwait were accepted, before the QM changed that.
No one calls OKC "Oklahoma" because that's the name of the state. I wish people would do the same for NYC, but that'll always be New York to most people. Anyway, OKC is accepted on here, so it's ok (no pun intended).
HatemAli's point I think is that most other acceptable 'city' cities accept the same name without city. no one calls the capital of Mexico just "Mexico", but it is still accepted generally accepted. This also goes for Kuwait, Guatemala and Panama. Obviously people still call the Vatican the Vatican but other than that...
That's because for the cities of Kuwait, Guatemala or Panama, the "city" at the end is not part of the name. Neither for official records or for popular use. It's just a disambiguator that can be used when there may be confusion. Meanwhile, Oklahoma City is officially named that way.
My strategy was just start west as those states are more spread out. All of the New England states and just the whole east coast are smaller states size wise, so I made a safe bet that they wouldn't be here.
It's only about 120 miles from Concord NH by the roads, 80-90 miles as the crow flies (Depending on how you measure--closest city limits, city centers, etc.).
