A New York woman said she has been unable to ride the subway since a rat climbed up her leg inside her pants. Ana Vargas, 40, said she was riding the train between 125th Street and Columbia Circle around 8 a.m. Thursday when the rat crawled up her leg and she had to take off her pants to get rid of it, the New York Post reported Tuesday. \"I\'m still nervous about it,\" Vargas said. \"I had to take pills to get to sleep last night because of what happened. \"I don\'t know what I\'m going to do to get to work, but I don\'t want to get on the train,\" she said.
