The author's Cully Long; he's one of the folks who put together the Dastardly Manhattan Puzzle Caches, some high-quality puzzle geocaches you might recall I totally failed to solve back in 2011. Maybe I should have read the book first. Oh, wait, it didn't exist. Anyhow. The guy knows this stuff.
Yes, yes, this will no doubt result in a book report… EVENTUALLY. After it's delivered… oh hey it's around Christmas… oh maybe it won't be delivered so soon then what with the Post Office delivering approximately everything in the next few days. Uhm, yeah, so here's an advance notice.
