This puzzle is devoted to groza528, a longtime fan who has encouraged me in so, so many ways – not the least of which was his decision to support me financially in the LiveJournal era of my logicsmithing "career", back when I decided to experimentally charge for access to my next 100 puzzles. groza528 actually sent me a check for four times what I was asking for, requesting access to the next 200 puzzles for himself and for a friend! I remain touched by this simple gesture of paying me money. Thank you so much, groza528.
