Private air charter company Stratos Jets conducted a study using Twitter and algorithms to find out which United States cities are the most friendly and the most hostile to tourists, and apparently, New York City is only the second most hostile city in the country. Not only that, but the city that beat us out is...wait for it... Arlington, Texas? What happened here? Who is even going on vacation to Arlington, Texas in the first place? The rest of the list makes more sense—third through sixth place is, in order, Las Vegas, Boston, New Orleans, and Orlando. The friendliest city is Chicago, by a mile.
