I used Google Maps to decide which of two cities I was closest to. And, as I said in my post, it came out very close – I am only a mile closer to one city than the other.
DC for me but it’s a couple hours away.
I live on the outskirts of Tucson. Not actually in the city limits, but not too far outside. I live in an unincorporated area of Pima County, but if I drive down the road a few miles, I’m in Tucson. It’s a residential area with plenty of surface streets and shopping centers, very well-developed. For all purposes, it might as well be in Tucson, we’re just not within the map boundary.
Right now I’m about 60 miles from Las Vegas, but I answered Sacramento based on where I actually live.
Live and work on the far north side of Indianapolis in the 'burbs. Been here since the mid-70s
Annie Xmas, I spent my youngun years in Bergen County. Washington TWP to be exact! 
Orlando is Florida’s second most populous metropolitan statistical area, but it isn’t on the list. I’m closest to Jacksonville out of Jax and Miami.
I live in a suburb of Columbus, although I have a Columbus mailing address.
