Size It Up Vehicles answer: October 21
The five Vehicles silhouettes for October 21, 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 48 ran from a Formula 1 Car (5.6 m) to the Hindenburg (245 m). The widest gap was round 5, Hindenburg against Big Boy Locomotive, at 6.1×; the closest call was round 3, Cat 320 Excavator against Cat 797F Mining Truck, only 1.6× apart — the kind of round that separates a 90 from a 60.
