...and to the open (west) end of the building...
...where the reversed direction and started moving into the building.
After the S-IC had gone far enough "around the bend," everyone scrambled from the west side of the grounds back toward the museum (located on the east side of the grounds), through the museum, out the front entrance, and down into the lower parking lot so we could once again see the stage.
A gate leading to the Saturn V Center was open, and we just went through the gate and up toward the building, still keeping what we considered a respectful distance. We did not go unnoticed, however, and since we did not have hardhats or steel-toed boots, some construction managers shooed us away to what they considered a "minimum safe distance."
They stopped the S-IC in the middle of the building so they could prepare the posts on which the S-IC would rest in the building. From first movement until they placed it in its staging location was about 50 minutes.
