Part of the reason for changing the lines around was because they needed the space where the line was for an exhibit. I think they were also trying to figure out a way to make the line go faster. All I know is, each time they changed it, we ended up farther back in the line. They did finally come up with an idea that made it go a little faster though. What they really need, however, is to put more volunteers on the pre-reg line. There were only six.
