I know it's a random and off topic idea, but I'd thought I would share it on here. I don't know if it would work as I've never been to CGA, even though I hope too soon, I thought of a maze location for CGA's haunt. I made a 3D Model in Sketchup, which I have taken pictures of and attached to this post. It is at the Flying Eagles ride, which would need to be taken down very similar to how Knott's did the mazes at the Balloon Race in Camp Snoopy for a few years. Tell me what you think and if you think it would work. The white floor is any place the maze could be.
All the white pieces on the ground in this pic, is a one inch thick floorboard.
A better overview of how it would work with the surrounding area.
Aerial view. Oh and in case you didn't know, the white roof is a tent, similar to Universal's Halloween Horror Nights in Hollywood.
