Geez, give up! You're wrong, move on! You generalized, claiming that all of the statements were "urban legend", yet they were provably correct except for one minor detail re. heating (which in fact exists on bridges).
Man walking on the moon, now there's an urban myth. Or the "single shooter" of JFK. But not mined bridges and emergency runways.
No, its not. An urban legend is something like "moth man", not actual facts that somebody gets slightly wrong as the mines in bridges or hidden military airports.
So generally speaking is it darker on the French side? No surprise there... (and all these street lights are powered by the worst nuclear power stations in Europe.)
