Damn straight, Captain - failure is not an option!
I know the feeling, TG, every year waiting on placement has me on edge. Some returning camps might be less anxious about it, but the bar does raise every year as camps constantly step up their game, and we generally re-imagine things from the ground up (airship outpost, idea deli, ziggurat, etc).
clocksnmirrors - what Savannah said, registration is not required to have a theme or build any art. For me though, as the camp and art has gotten more involved, setup time is an issue. Registration and placement also means an opportunity to arrive before the gates open and get cracking on building stuff.
I wound up circling back and ordering a second big piece of aluminet yesterday (caution: don't try this at home, that stuff is spendy). That way I'll have solid coverage for the entire courtyard. Work also continues on modeling the camp in C4D. I've got a love/hate relationship with that program - awesomely powerful, but it's a nest of pigs in the way of things getting complicated fast.
