Past Self is writing this before heading out on a vacation to Yellowstone. Hopefully Future Self will have arrived back in NYC on 7/13 as scheduled, and will be feeling chill and rested after a week of hiking and eating steak.
None of which is germane to you solving this puzzle, of course. Just wanted you all to know that I make themeless happen even when I’m on vacation. (Also not germane to this puzzle: Happy Bastille Day!)
