If you are planning on using public transportation a lot when you are at PLU, you should consider getting an ORCA card. The ORCA card is a pre-paid bus pass that makes traveling easier and cheaper. Visit http://www.orcacard.com for more information.
If you are over 18 years old and have a driver's licence, take a look at renting a Zipcar for an hourly or daily rate!
