My first starting point is "How do I signify Paris, Belgium and Amsterdam in a graphic way?" Or the route. Or France/Belgium/Netherlands?
Paris or France is easy: Eiffel tower. Amsterdam or Netherlands is easy: Tulip or windmill. I will avoid making use of red lights or cannabis as a symbol here: I might get arrested in France with a photo of a cannabis plant on my T-shirt, and we don't want that. But what to do with Belgium? French fries? I found out that the saxophone was invented by a Belgian.
Trying to put the Eiffel tower, a saxophone and a tulip together with simple lines, however, does not create the simplicity I'm after. Especially if I should put a bicycle in there - which incidentally is also another great symbol for France. Nothing screams "France" more than a bicycle.
On another note, I went ahead and bought a new bicycle chain. It was cheaper than getting rust remover and oil to treat the old one.
And finally: Route Paris-Creil
