The subway is great.  $2.75 can get you anywhere on the island, over to Queens and Brooklyn even.  A little dirty, yes, but thats what you get for the same price as a slice of pizza. While there are other forms of transportation (like Uber) which are cleaner and more convenient, who's got the money to Uber everywhere you go?  An besides, Uber isn't historic and monumental like the subway system is. It's been around for over 100 years and hides some interesting secrets we want to share.
