-Theres also only 3 more clues! Because when I visit the hersheypark.com / 2017 website and scroll up, theres a 12345 and the 1 and 2 are purple while the 3,4,5 are still blue.
-Theres also markings labeled TB3 at the area where convoy is, TB3 could be tower base 3, meaning there may be 3 towers in a triangular formation...(I saw this on facebook in the comments, someone posted the picture in the comments for clue 2 if you want to see it)
