PickupPal.com: Online Carpooling Resource
I ran across this site on TreeHugger: www.PickupPal.com. Now completely advertiser funded site that connects people for carpooling/ridesharing. I’m not affiliated with the site, but I did post my daily drive to work.
From the site: Launched in January 2008, PickupPal allows a private vehicle engaged in a transportation event (a one-way trip from A to B) to be matched intelligently and dynamically over the Internet to a pickup location (someone or something) along its planned route anywhere in the world.
