A group of Christians carried a cross and some signs over the bridge. They also had a booth setup at the event. The group actively tried to gain converts throughout the time, going up to people who probably weren't their to be told the "truth". Of course, it is their right to do so. Most just ignored them. To be fair, they weren't the only religious group. A Blackfoot Elder and spiritual leader was part of the formal ceromony, blessing the bridge.

I believe this is Zombie Jesus. Later on (not seen here) the procession passed by some Christian evangelists trying to convert people on Stephen Avenue Mall. I kind of wandered what they thought of him.
