Thanks re 27A, Simon (#70) - I had a PDM after your hint & I really laughed out loud. Love the simplicity of using the word "go".
Also liked 10/17 once I got it - I gather a few of us are only 10 or so years from 10, 17.
Still only 2/3rds through. Tricky one. Everyman was so easy by comparison.
Thanks for all the v helpful hints.
