Noreascon Three, Boston -- Arrival at the con from the airport a split-second before I was scheduled for a program item turned out to create a convention-long misapprehension: a security guard trying to stop me from getting into the program area without a badge was turned by witness Karl Edward Wagner into a report of my being bodily hauled away! Working Program Ops turned out to be a breeze due to the terrific organization by the people running it (and the invention of the "little blue dot" for service above and beyond). The open seating for the Hugo ceremony worked very well and I would copy it years later when it was my turn to run it!
As usual for Boston, a terrific worldcon. This was my first experience moderating a panel that I myself knew little about but it went fairly well and I've done it several times since. This was also the first con at which I took some time off to go to a local baseball game (being as I was dating a baseball fanatic at the time and this was one of the bribes I presented to get him to go with me to worldcon.)
