Use the Upass
WashU gives each student and free UPass which allows them to travel on the MetroLink (kinda like a subway I guess) system for free. Don't be lazy, take the Metro to and from Lambert Airport. It's not a far walk at all and it will save you a ton of money, especially if you can't find anyone to split a cab with you. WashU is in a nice part of town, you will not be mugged on your way to the MetroLink station. That being said, the Metro is not good enough to get you to every part of the city. Taxis are needed especially if you are going to bars/clubs as a freshman (b/c frosh can't have their own car).
