I'm 23 female looking to get from LGA to Lower Manhattan at apprx 7:45 on a Friday night. I need a safe/cheap way to do it. I can afford a taxi, but would rather spend the money elsewhere. I would like to take the M60 to the 1,2 or A,C metro. My concern is being alone, w/ luggage in the dark and unfamiliar with my surroundings. Is this a safe transfer to make? Is there a better route to go?
