I live in the Texas Hill Country, northwest of San Antonio. But I work in San Antonio. I'm the District Engineer for a very large construction company. I am a licensed Professional Engineer, the head of the engineering department for my District which covers three states. My job is primarily in our office, although I sometimes visit jobsites.

So it's not a terribly formal workplace. The office staff tends to wear 'business casual' attire, which is barely a step up from jeans and boots.
