Pat,
I haven't played up north in NJ during June or July, but I can tell you Greate Bay is playing firm as well. We're getting fliers from the rough, and on many of our holes where one can run it in, I've found the play has been to club down one and run it on.
I had Jason Mandel out on Thursday and the staff was syringing certain spots of the course, not all. We had a good time and enjoyed the firm conditions.
A ball from the fairway, say, with a short iron will leave a small pitchmark and you would be able to hold the green. Long iron, hybrid, or fairway metal may release through the green.
We have a few "backboards" in our greens (5, 7, 8, 10, 12, 14, 18) that I would like to see a little firmer or quicker, but otherwise, course is playing great. Come down.
