Nature’s Camo Gear
My brother used to work as a kayak instructor in France, usually coaching British city kids. One of the things he used to tell the kids was that in ww2 the French used to paint sycamore trees in military-style camouflage so the German bombers wouldn’t see them.
And after the war the French decided to carry on painting the trees as a tradition, hence why they look the way they do. Apparently a lot of them believed it. Story credit: Reddit / WibblyWib
