I would imagine that the foliage in PA will be down in the next week or so. This is a pic of my foodplot in PA taken last weekend, I think it was at it's color peak right about then. Once some frost hits those leaves they will drop quickly.

I hope for 2-3 good frosts in the next week, this food plot is almost entirely brassicas and they are bitter until they get a bit of frost. Once some frost hits it, it shouldsweeten a lot, then the deer should be in it pretty heavy I hope. They use it now but not much.
