I've graded Advanced Placement Computer Science exams for the Educational Testing Service for many years. I began in 1987, but was out for 1993-1997. It's 7 to 12 days of work (depending on my position) each year in late May / early June.
The APCS Reading has moved around during those years. First, Trenton State College (NJ), then Clemson University (SC), then back to Trenton (where the same school has a new name, The College of New Jersey), then to convention centers instead of college campuses, in Louisville (KY), and finally, the last few years, in Cincinnati (OH).
I haven't previously written these up as travel. For one thing, since work is 8 am to 5 pm every day including weekends, we don't get a lot of time to sightsee. Also, I only have a few photos from earlier years.
This year, since I'm still trying to lose weight, I did do a little hiking in central Cincinnati a few times after dinner, and, since it was my last APCS Reading, I did take a few photos. The link is above.
