Size It Up Landmarks answer: September 24
The five Landmarks silhouettes for September 24, with the true sizes. If you have not played yet, this page is a spoiler — play these five first, then come back to argue with the numbers.
Day 21 ran from the National Monument (Monas) (132 m) to the Akashi Kaikyo Bridge Main Span (1.991 km). The widest gap was round 1, CN Tower against Akashi Kaikyo Bridge Main Span, at 3.6×; the closest call was round 4, National Monument (Monas) against Statue of Unity, only 1.4× apart — the kind of round that separates a 90 from a 60.
