I notice it's worse in cities with extremely dense urban cores, like NYC. There was a distinct smell (not just garbage, but something I basically call 'the NYC smell' in my head) in many parts. Other cities never seemed quite so bad; at least not bad enough I can still remember that smell.

I've never been to NYC, but I've heard that waste management infrastructure is not great there. Could that be contributing to bad smells?
