Well, I haven't quite decided yet, but if you and @JoeB are going, I should really make the drive. That is why I asked here if anybody was going. (I know it's even more of a drive for him.) I don't think has been well publicized. It is only a max 300-person event. I think I only saw it in passing on Facebook somewhere—which I only ever look at for Trek news!
My understanding is that GSchitzer from the TPZ is going to have a fair number of props on display there as part of the open house at New Voyages. He has been nudging me to try to get him a TMP scanner or two in time to show at the event, but the 3D printing issues have gotten in the way.
