Had July 2008 beans make 57 bpa, had July 2011 beans that we turned the combine around whenever the yield monitor hit zero to save fuel- put 180 acres on 3 trucks.  That's the crapshoot you are looking at.  FWIW, I will plant till July 3 because I have some replant stuff and some partially planted farms, but July 4 will be for drinking beer and July 5 probably for washing and unhooking planters.
