Growing Open Pollinated field corn

I have been growing OP corn for over 12 years .
Each year I look forward to selecting next years seed ,and seeing it transform into a unique corn.
I started out with 2 varieties and now have 5 in the genetic mix .
Each has it's good and bad traits ... such as lodging , OP corn is known for this (by some farmers)
The trick is to get the traits you want in one plant and then make it stick.
This is better than playing chess with a tough opponent.
and no 4th of July firework is ever so dazzling than seeing that one of a kind ear of corn.
I'll name a few parents : Bloody butcher, Blue Clarage, Texas gourdseed ,and a 100 yr. handed down corn from Tenn.
Anyone else raising OP.
