From the company website:
In 2013, Westat is celebrating 50 years of research and analysis, contributing to numerous advances in health, education, the environment, and public policy. We are commemorating this anniversary with a number of events throughout the year to recognize this milestone, and we have adopted the tagline “50 Years … Improving lives through research” to highlight the year.
One of the events mentioned was a big party under a tent in the parking lot. It was quite a party, actually, and the food was excellent. It would have been nicer if it wasn’t quite so hot, but that’s another matter. Earlier in the day I took this picture of the tent from the rooftop terrace.
