The 51st Street Stench Corridor

Have you ever transferred from the downtown 6 train to the E/V trains (or vice versa) at 51st street and Lexington Avenue? If so, then you have traversed the most disgusting underpass in the Manhattan subway system (I can't vouch for all of the outer boroughs). This little walk of shame has even made me consider not bothering to transfer sometimes or taking an alternate route. It is a combination of vomit, doody, urine, and some special ingredient...maybe B.O.? I can't quite put my finger on the smell, can you?
