In one section, I commented on a certain bridge in downtown Portland, Oregon. It's one phrase, but if I'd gotten it wrong, anyone familiar with Portland would immediately distrust other things I have to say. The research for that particular remark wasn't laborious, but I did sweat it a bit. In these times, when you ask a city engineer about which bridge in the downtown freeway system would really botch up the afternoon commute if it were closed for any reason. . .well, I'm just glad nothing happened to that bridge after I asked the question.
Ahh,the fun and games of research.
