Concrete Pouring & Fibonacci Spirals

The cement trucks were lined up ready to move into place when the last one emptied its load.  I didn't have to worry about losing that perfect moment to sketch something because it was the same scene over and over.

I've been thinking about Fibonacci spirals and golden proportions lately, and I imagined that the arch of the long arms pumping the concrete into place was roughly creating the famous shape, and some of the buildings proportions and relationship to one another seemed to fit too.

It was beautiful weather for sketching, and the great company of fellow sketchers added immensely to the delight of the day!
