I'm posting over here because I'm not convinced that what is going on at the back side of Planet Snoopy is a maze. I could be wrong.
I went to Carowinds to scope this out today and here is a quick rendition of what I saw. The blue dashed lines are where there is a lot of white spray painted dots that appear to mostly be marking power boxes, edges of trees, fences, curbs, etc. There are also some orange/red spray painted dots interspersed. The red spots are where I saw survey markers. Two of them are nails driven into pink tape and then into the asphalt. The two blue ones circled in red are where I saw orange flags in the ground. They could have been there all season for all I know. (thanks to JamminJ for indirectly helping me figure out how to post external images!)

Here's the stake in the middle of Joe Cool's Driving School:

Here's the stake by the flyers:

Here's one of the flags back by Afterburn:

There also appears to be something going on in the area near the entrance to Kiluaee:

Based on the size and location of all this, I predict that Dinosaurs Alive is going in this area for 2013.
