About 15 years ago, I worked at a small tech/political agency in DC. We got a new office just off NW 16th & K near the lobbying & financial areas. While I was setting up the server closet, I found a rolled-up blueprint from the office design. We unrolled it and... turns out it was built by Enron. Ken Lay had just died, so we always kinda-sorta felt haunted by his ghost.
