Mystery Field

I've given up trying to figure up what's going on with this field (here, here and here, for instance). It's supposedly owned by a strawberry farmer and there's even a sign saying as much. 

But sometimes there's strawberries growing - then they get plowed under. Then there's corn growing. Then the next time Sam and I walk by- gone! Then there's something growing which may or may not be squash... or pumpkins... or whatever. Then- same story - gone!

I've stopped trying to figure it out.

They're doing this to me on purpose. They are my enemy.
