Congrats PJ.
Can you, or anyone else out there, give me an on-line reference for Colson (or for that matter Gybels)? For all my work on this puzzle, I never ran across either name on-line (not once), and, even with the name(s), Googling turns up nothing (except a correct Gybels answer on a previous puzzle by woodinsight).
Thanks, in advance, to anyone with an informative link.
