There was a picture hanging on the wall in the hallway of the apartment building where I was staying. I can't explain why, but every time I entered the hallway, I had to stop to look at it. It wasn't anything special, the picture. Actually, it was rather commonplace. It showed two waterfalls heading out over a cliff. A rainbow was showing close to where the falling stream hit the surface. I suppose it reminded me of why I had even come here in the first place.
