Flying into the triangle is just as confusing. Always ruffles my feathers to hear people claim they were in “Raleigh Durham” over the weekend. Raleigh and Durham are 2 separate cities - 20ish miles apart! Yet because the airport is “RDU” the two get lumped together and people make the mistake of claiming to be in two separate cities at the same time.
Greensboro also has an airport - but I can’t lay claim to ever having flown into or out of Greensboro (the triad). Though Jim Boeheim has made it clear he has no love for Greensboro or the Triad.
