From looking at pics I took on the boat ride through the gardens, it appears that they are adjusting the count of harvested tomatoes on a regular basis, as you can readily see the previous set of numbers in shadow behind the current ones on the whiteboard sign they are using. That was the count as of 2006/01/25.
My favorite part had to be the Mickey head pumpkins they were growing! From the picture below, it appears that as the size of the pumpkin increases, more and more fasteners are used to keep the two halves of the form from separating. For the nearly-complete pumpkin of the three in the foreground, it appears that they added a metal reinforcing band as well.
