The path ended up being part of the old sewage system and so I was able to walk though the sewage tunnels.The lighting in the tunnel slightly distorted my perception of color and space. The lights on the ceiling of the old sewage pipe made it look as though fire was racing toward the entrance, and it was difficult to see if a person was going towards me, or away from me. These two children ran through it over and over, and tried to race up the walls, completely fascinated.
