My corn is all 6' tall already and I noticed coming home from church that it was starting to tassel.   That's pretty much 2 weeks ahead of normal for us.   I'm not even sure if that's a good sign or bad, but it sure looks good.    Even last year when the corn looked like a giant pineapple field it never tasseled this earlier.   As long as it stays wet I''m not complaining.

I was down in Lyon Co, MN last week and things sure look yellow, especially the beans.
