Do you believe in Santa?

Do you know what SantaCon is? Apparently, every year there is a mass gathering of people dressed as Santa Claus in the cities of San Francisco, New York, and London. I just learned that this year it was today. It looks like fun! I have to say that New York inspires me to do these kind of "crazy public" things. I wonder what the psychological/social factors are. I am sure that if I still lived in Mexico City, I wouldn't even consider it. If I move to Frisco next  year, I will do my best to go... at least with the Santa hat! (provided I remember, of course).

Would you do it? If you have done it already, what do you like/dislike the most from these events?
