knee high by the 4th of July

Sunny. Noticing on the drive home last night that the corn in some places is really high this year, over 7 feet in some places. The old saying "knee high by the Fourth of July" is usually pretty much of a joke in these parts. If the corn is a foot tall by the 4th, that's pretty much par for the course. I noticed this year that the corn actually was knee high by the 4th. Maybe growth patterns in Vermont resemble the midwest because climatically we are starting to resemble the midwest. Another global warming update it seems.
