re: If you haven't been to crystal bridges museum

Worked on that job from start to finish. Those suspension glass walls on the two main bridges are the only ones in the world. One early morning I was in charge of making a hypothetical mathematic equation "work" in the field. So technically I have done something no one else has ever done. Even more rare than walking on the moon.

The suspension cables that support the glass walls are 6" thick and weigh 50lb per foot. They also tighten or sag 1/8" per 1* F at a relative temp of 72*. Working with Moshe Safdi was one of the highlights of my career. If you have any questions about the site I can probably fill you in, if they don't interfere with the NDA.
