Stagecoach volunteer looking for drive to SC from San Diego!

Hi there, I am a Canadian traveler who will be volunteering at the festival this year but I have yet to find a drive up from San Diego. I am willing to help out a bit with gas expenses if need be. I only have one backpack so I don't take up much room. Please let me know as soon as possible.

Thanks in advance!
Hopeful to meet some of you sweet people :)

P.S. I am also looking for a drie up to Sacramento after the festival, if anyone can help out with that.
