Two seniors travel the world
Too bad you'll miss the Christmas market. I really like the one in Mainz -- great setting, excellent sausages, nice variety of goods on offer, and not so crowded that you feel like you're being propelled by the crowd. Enjoy the rest of your time in Germany.
We also missed the Gutenberg Museum, as it didn't dawn on us until today that it's closed Monday - all the more reason to return!
