 Mexico City, London, and Paris rank second, third, and fourth. But eight of the top 20 in the world are here in the U.S. with Chicago, Los Angeles, Boston, Miami, Philadelphia, Washington, D.C., and Houston all cited. Now, I absolutely agree with Chicago and Miami as Mary and I have spent a lot of time sitting in traffic in those cities. And yes, L.A., Washington, D.C., and Boston are terrible too. But New York surprised me because the one thing I always say about living here is we have about 10 different ways to get around so you can always find a different route.
