Crammed with people with backpacks and briefcases all over the place plus homeless wrapped in coats in July and not enough cops to go around. They've even cut back on toll booth clerks.

At least in New York little visible security. I hope they have some sort of detection system but I doubt it--the system is just too big.

Londons Underground is similar in size and age to New York.

Those poor people.
