Leaves Left

It's autumn here in Berlin.
I can't speak for the rest of Germany (I don't have the correct forms from the Standesamt) but it's definitely autumn here.
Last night a real screamer of a wind storm was happening outside - had to turn the tv up to block it out - and this morning there are almost no leaves left on the trees.
Something like that could bring a modern city to a complete standstill, but here in Berlin those naughty leaves are dealt with most severely.

It's only noon and already the teams of men in orange overalls driving insectoid little orange street cleaning trucks have hoovered up the majority of the mess. The leaves that don't fit into the insect trucks are left in great piles at the ends of each street, to be collected later by much bigger orange mother trucks.
Bafflingly, the huge piles of leaves stay where they are despite the wind's attempts to redistribute them.
And why? Because the chaps in the orange overalls spray the leaves with magnetischerblattkleberspray (magnetic leaf glue spray).
Leaf chaos under control!
