Before leaving Luxembourg today, dad filled up the gas tank at the gas station near the border because he said the price of gasoline in Luxembourg was cheaper than that in Germany! (Euro 1.19 vs. Euro 1.43) while mom shopped for good wine and coffee. On the way back to Munich, we stopped at Speyer Cathedral, another world heritage of Germany, which was beautiful. Before we left for Munich, I spotted the park nearby with a lot of airplane but unfortunately we had no time to play today!
