Guilty as charged. I drove by Liege - twice - this summer, without even considering to stop. In my defence, I can claim time shortage and fatigue - it's a four days drive from my home to Normandy, our destination on that trip. Then, a visit to any European city by car is today a problem - you've got to find out whether there are any green zones where you can't get without paying, places to park, etc. And, finally, I said to myself, OK, I drive in, get out, look around - "Cool. I'm in Liege" - and drive on. What will it give me? Gunmaking centers require a dedicated trip, w/o unenthusiastic family members by the side. Perhaps some day...
