I was wondering about that. I remember asking a few people if they knew who had organized the event so I could get the "official" who/what/why, but no one had a clear answer.

Truth be told, I suspected in advance a quiet hijacking of the Saturn birthday march by the usual suspects of Downtown-For-All for the usual issues. When it was over, I walked away with the same suspicion. Unfortunately, no one in the march seemed to be asserting themselves on the matter, or I'd have interviewed them.
