greyhound tickets: Im almost 17 years old, and currently on my own, and I was planning on catching a greyhound to go somewhere with higher paying jobs, so I can start a new life. But all I have is a highschool id and my social secruity card. Would that be enough id to purchase a ticket.|||I don't think they even ask for I.D.. You should have your birth certificate if you are striking out on your own...you willneed it for other purposes as time goes on...like to get a drivers license or state I.D.card. Be careful and wise...and good luck.|||I dont think so because a school id just shows you age,grade and IQ.?!
