Germany
I'm going to Germany in August for the CCC's (blocked by N2H2 as "Illegal"!) biennial Chaos Communication Camp. I've never been to Europe at all. One of my priorities, I hope, will be to visit my grandmother's home town, Herborn. (I didn't know that J. A. Comenius, the human rights and peace advocate, studied there, but I did know about "annihilation of the Jewish Community (1942)".)
I have a recent postcard of Herborn on my wall; the main street looks practically unchanged from the 1920s. I'll have to go see if that's still true.
