I've attempted to take the Greyhound four times. Twice they gave me the wrong address to take it from. Once from Irvine, where I was told to go to a new transit center that wasn't open yet. The other time from San Luis Obispo, which has no actual transit center, although it has a train station, and county buses leave from city hall. I was told the Greyhound left from a Texaco station right off the highway. I made it out of Irvine the same day (hitchhiked), but I was a day late out of San Luis Obispo (took the train), and had to reschedule a connecting flight.
