I might go if I don't have to travel for work. I know I have to register by sometime in July (or pay a bigger fee) and I have not done so yet. I want to do a scene with my astro-miners creation but I have not completed as it is much bigger than the others I have done. I also am working up some Blacktron ideas but I doubt they will be ready by July. I unfortunately dont get to much lego time.
Are you thinking of doing a modular moon base? If so I got a space-diner that I could easily convert if I know the moon-base specs.
