Carpooling is a great way to save transportation costs as well as enjoy some company on the way. It is also an alternative to public transportation for those who don't own cars, such as most students. Carpooling often implies shared commuting (a group of people making the same trip on a regular basis), while rideshare/rideboards are usually used for one-off trips.
Ride Boards
Craigslist
The best way is to use the
rideshare board on Craigslist, as many Davisites do. Another possibility is
CarPool World.
MU board
There is a ride board in the Memorial Union, just down the hall from the information desk -however hardly anybody sees it or uses it.
ZimRide
Yet another possibility is
ZimRide, as it interfaces with
Facebook so you can both get a sense of the person you're ridesharing with, and have a way of broadcasting your ride (or ride request) via Facebook feeds. If you already have a facebook account, you can just use that to log in.
