You have some interesting points, I won't argue about because my post a response to what blog was about. But I must disagree with you on the matter of cleanness, just the look of things alone is disgusting and yes the streets of NYC is dirty and in many cases disgusting. The cars like I said in most cases are tolerable as long as you're not in on someone just urinated in. This probably happens once everyday ( primarily on lines from the outer boroughs) because some people make the subway cars their room and toliet.
