Engineers are not always held in very high esteem. I was at a recent rep firm show-n-tell and overheard a group of installers excoriating engineers as a class of human (along with interior decorators and architects) for being know-it-all, arrogant, impractical, having no sense of reality, and generally impeding the installation. I kept my distance, but I was thinking about throwing a log or two on the interior decorator and architect fires.
