I really like the "one way street" sign in this blog post because it reminds me of our first trip to Germany, where we were bemused at the incredible number of roads Munich had all named "Einbahnstraße".
Reminds me of when I went to Brussels the first time, trying to travel to Leuven (where my friend was staying). All the buses were going to "Geen Dienst". That's a popular destination I thought to myself.
Means "Not in service", for those wondering.
A friend of mine made the following remark when she was little, travelling on the autobahn: "darnit, Ausfahrt must be one huge city, since all the exits are pointing to it"
