Frost on your corn?

I am guessing some of my readers to the north had frost and or frozen corn.  Everyone knows that at three leaf stage or younger the growing point is below grown, so some black leaves are not really a problem.  Some of the really early corn was bigger than that.  Temperatures in Bloomington and Decatur got as low as 29 last night.  Probably lower in some places.  A few people have corn in the 5 and 6 leaf stage.  If it froze, I suspect it looks terrible by now.  So now what?  I say if the stems are still ok, wait a few days.  The growing point even above ground is somewhat insulated.  If it is not coming out of it in 3 or 4 days, then destroy it completely before replanting.  You don't want those stray larger stalks messing things up.
