We had lots of 15’ drops in tilt-ups to office build outs at 9-10th AFF. After 
Nisqually earthquake I don’t think I saw any failures. A few broken suspended 
ceiling tiles. Yes, a couple goosenecks did roll, but that was on ESFR, near 
roof level, and is another story.

Quite a few other breaks.

Best.
