Well, if you do go, you would be able to meet me and see the Sincpac for Civil 3D in action. I will have a booth in the Exhibit Hall, look for Quux Software. There do seem to be fewer C3D related classes this year, however. One thing to keep in mind, if you have any specific things you'd like to bring up with the C3D development team, many of them typically attend AU and are actually good to talk with.
