I was walking around campus before class and saw posters for Carpool Week. I wanted to see how the prizes compared with the $75 grocery prize they offered for bike to work week (which occurs during the summer break, so I couldn't participate this year as I wasn't taking summer classes).

The university was offering 2 - $500 grocery cards. Plus the provincial sponsors were offering a 3G ipad, Wifi Kindle, a GPS and $700 in gas cards. The only way you can participate is to commute by car. People taking the bus or riding a bike are inelegible.
