I happened to be in the Rayburn House Office Building this afternoon, and since I had earlier been thinking about removing Death Valley from my vacation itinerary, I decided I'd try to pick up some tourism information about the Central Valley. (Members of Congress frequently keep tourism information about their districts in their Washington offices.) Unfortunately, I had no clue as which members represented that area, so I checked the directory for the member of the California delegation whose office was closest to where I was, and stopped in that member's office to find out who among the members from California represented the Central Valley. The name I was given: Bill Thomas. So I went to his office, and was told by a polite young man that he had nothing that would be of any use to me. So I thanked him and left.
It was only much later that the perfect exit line occurred to me: "No need to call the Capitol Police, I'll leave quietly." Crap! Maybe next time.
