The pic above reminds me this interesting, nowadays nearly forgotten historic episode:
the coffee smuggling from Belgium to Germany in the late 40ies:

because the police used some -very early- Porsche 356 with iron brushes under the front (see pics 2, 3, 4)


@antp, @chicomarx, @Exiv96: what's up with the "Belgian armoured car, make Blendy"? (pic 11)
I've never heard that name.


What make is the large US Limousine on page 12?


To pic 18 and 20: "This Dodge car was owned by the Belgian Jupp Hons, who smuggled over 30 tons coffee to Germany.


Coffee smuggling was a big business back then, because there was a high tax of coffee in Germany.

The tax still exists, but it was lowered
- but it's still worth for Germans, living close to the border to Belgium and the Netherlands for shopping coffee there.


In that Belgian-German border area there still are some funny bilateral topics.
Not as bizarre as in

but stil intersting.
So there is a bicycle route on Belgian ground, going through Germany:

There is also a German federal road for 3 km on Belgian ground, so it has the Belgian speed limit 90.
The road has no connection to the Belgian streets.

When you enter the parking in Konzen and walk in the nature reserve Hohes Venn/Haute Fagne, you are passing 4x the German-Belgian border within 300 meters.

Our doggie made me pondering, when she made a big poo there:
the dog cowered in Belgium, but the poo plopped on German ground - where I had to pay the punishment, because I didn't pick it up?
