Thanks everyone for your nice comments.

Priscilla - I downloaded In the Garden of Beasts on my kindle before we left, but haven't started it yet. I am about 20% through Berlin 1961 by Frederick Kempe, a very well written and extremely readable account of the year the wall went up. The "enhanced edition" includes 41 videos from the NBC News archives which are viewable on the kindle app on my iPad and make history come alive. I highly recommend it.

Marcie - we did not see the 1936 Olympics stadium which I gather is used for soccer games today.
