I went out right after reading your reply, and I think all of my rye and most of the wheat I saw was hard already too. Ended up broadcasting into it anyways and mowed it down. At a minimum, the red and white clover should come back nicely before the cereals take off. Hoping some brassicas can find a home in the tire tracks, but not overly confident. Left rye standing a bit too long last year in an old garden area and rolled it down. Came in thick and did a good job smothering most of the competition, including the clover I had broadcast into it. Not the worst result, but not quite what I was trying for.
