Pasadena Water Fountain on Lake Ave!

So I was driving to work today, and I looked at the horizon and saw this thing that looked kind of like a ghost. 

Keep in mind that I am like 4 blocks away.

So I approached it and it was enormous!

So I got off the freeway to see what happened and there was a major traffic jam.

This is one of the bigger water fountains I have ever seen.

So I got out of my car and took some more photos.  Note the blue suv on the left.

I suppose this guy has something to do with the fire hydrant in front of it and the fountain behind it.

Here it is from another angle.  Whoa.
