Bell Curve Beans

It's the weirdest thing with the beans that are growing through the space-age mulch; they seem to be growing in a bell curve pattern.

The tallest beans are in the center of the row and the size of the plants gradually decline toward both ends.  In fact, the plant on the extreme right end sprouted but doesn't look like it's even going to climb the string at all.

The plant in the center, on the other hand, is looking for new worlds to conquer.  I told Cindy that it looked like it's trying to figure out how to get to the telephone wire six or seven feet above it.

We have no idea why these plants are doing this.  It could just be a coincidence; it could be something to do with the heat coming off the mylar.
