Pi. . . or is it?

I was in Portland the other day waiting for the Max train. It was a tunnel one, so I had to wait. . . in a tunnel (go figure). Well, on the wall, lo and behold, was pi! I quick snapped a pic on my camera phone before I had to hurry off and join my group. This morning I was all excited to blog my pi adventure so I uploaded the picture to my computer and looked at it. To my shock/amazement/horror/disgust, only the first line is pi! The other lines have nothing whatsoever to do with pi! WTF?!?!?!? I'm going to write a letter to the Max train people and pursue it, I'll keep you updated. . .
