I'm flying in on Thursday afternoon and leave Saturday morning. Since i don't have a car, do I need to register? I saw that there is spectator prices of $5 a day - $10 for me. T-shirt will be $15. So for an extra $10, I get a plaque and goody bag. Am I correct? Is there anything I'm missing? I just need clarification before I sign up. Also, the "Updated Registration" doesn't include the "free" t-shirt size.
