Yesterday on the 4th we drove both west and north of Waco. Saw a lot of corn fields that had recently been harvested, but without exception each cut field I saw had three or four rows left standing together, 100-200 feet long or so, usually more or less out in the middle of the field (not at the border). A few large fields had two or three sections of rows left standing. I can't recall seeing this before and was trying to figure out what the reason or purpose was. Anyone know about this?
