Extremely accurate. L3Harris pumped so much ad money into the walkways at Dulles I'm surprised they don't have naming rights to a terminal. There was a time not too long ago where you couldn't listen to WTOP without hearing Mitre and ManTech ads with the term "Digital Twin".
Which like, seems entirely rational? You're a sales team pursuing a deal with an 8-9 figure outcome, of course you would buy a billboard on on the decision maker's commute, it's a rounding error expense.
Completely rational. It makes sense that an area with a highest concentration of defense/government contractors would see a ton of ads geared towards the procurement folks. I grew up in the beltway and interned with some bigger defense contractors in college, just pointing out that it's a phenomenon unique to the DMV area (with some more memorable examples).
