For 4 years in the 1980s we lived just across the Rhine in a small German town called Lahr-Schwarzwald. Saturday morning if we needed red wine and cheese we would head directly west to the nearest border post, usually unmanned, where a back road crossed some of the Rhine locks, and in about 25 minutes be at a very large shopping complex called Mammouth. Afterwards we would head another 25 minutes or so north into the city centre to visit one of the places you mention. So good to see them all again in your post!
