We finally found the Dharma booth! Now, if you don't know, I am a Lost geek. The episode that did it for me was the third episode of the first season. The moment they revealed that the wheelchair had belonged to Locke, I cried tears of astonishment and fell in love with their storytelling.
Anywho, we went up to the booth and discovered that the morning testing was all full up, and they'd be making appointments again at 1:00pm.
In my mind, weeks before we went to Comic-Con, I had pictured an area with about six little tables to take the test, instead, they only had one booth that could only be used by one person every 15 minutes. Before we left, A gentleman handed me a flier.
Here's the back. Look, an origami swan. I guess an origami hydra would've been too much to hope for.
So we wandered around some more.
