Occasionally you get quote-unquote, lucky, that something ahead of you maybe slows down, if there's a vehicle that has an issue and so everything stopped for a little bit. Sometimes you have those rare moments where you have a little bit more interaction with the crowd. The phrase that kept coming to mind during this project was drive-by science. You don't have time to stop and do stuff with it, and so in an organizational sense that was a huge challenge of, what are some demonstrations that have a very short time to observe that can be on the move and don't require electricity, and aren't going to be so cumbersome, but it's going to slow everything else down. So it presented an interesting problem. But in terms of the crowd reaction, the crowd had a great reaction to everything that we were doing, really everything that was going on in the parade. I think partly that's a reflection of the characteristic of DragonCon, a conference as a whole. Everybody at the conference, with obvious outliers here and there, but everybody at the conference was always very supportive of everybody else at the conference.
