I was looking at some of the narrow and wide gaps in the balk/guess rows from the corn he planted this years. He'll be 82 this Sept. After not having him around last fall with harvest.  I'll be proud to harvest any corn row he plants.  I'm sure he's planted well over 65 corn crops. 

He was telling me Sunday he started with a 2 row planter on a 9n.  He didn't need markers. You just drove in the tractor tracks. So, he started planting without markers and now with can/could plant without them.
