Start here and fix the problem. BUY A FUCKING CAR OR MOTORCYCLE. And figure out a way to afford it, (maintenance, gas, insurance).
Who the hell wants some fucking leech sucking them dry for free rides all over SoCal with gas prices well over $3/gallon?
You need to pull your own weight. And if you can't do it w/r/t gas and transportation, I sure as hell doubt you'll carry half the group gear, pull your weight leading, and so on...
