Photo by myself around 39th Street and Seventh Avenue.
Oh what a familiar sight.
For non-New Yorkers, please note that the light at the top of the oncoming cab is not lit up This means the cab is not available - it already has passengers, or the cab driver is on break.
The cab is also unavailable when sides of the light are on. Tiny words will appear, saying 'Off Duty'. Only when the number of the cab is lit, in the middle of the light, is it available for hire.
The best way to get a cab is to stand at a street corner, near heavily trafficked street. This can be tricky when you're on a quiet street in the Village. On rainy days and during rush hour (8:00-9:30 am, 5:00-7:30pm), it's a bit harder to find a cab.
By the way, if there's ever a time to visit Times Square, it's around dusk.
It's a magical time - the sky is an electric shade of blue, growing steadily darker. Headlights switch on, and all the towering signs are eye-poppingly bright.
