Edit: I found a ride with a nice married couple that's flying into phx and driving from there. They only have a 4 door so they don't have any extra room for you guys that are still looking, sorry! But I can see a bunch of new threads popping up about carpool too coachella from phx/tempe so I'm sure It'll all work out!
Myself and my girlfriend are looking for a ride to Coachella (weekend 2) from Tempe/Phoenix, Arizona. We're both easy going, love music, and are very excited for Coachella! Feel free to PM me or email me at: firstname.lastname@example.org
We'd be happy to chip in for gas/food.
Can't wait to be on the polo fields!
