IG, I couldn't believe my eyes when I went by a cornfield that I go by almost everyday. I think it was Sunday when I looked at the stalks. I thought they will never be knee high by the 4th because at that point they looked to be 6-9 inches tall and scrawny. Well, today when I went by it put a smile on my face. Those things are well over knee high.
I know our corn grew 7 or 8 inches in the last 24 hrs. It's almost shoulder high.
