Mog and I were pretty tired after the conference, too many early starts, so we didn't get up to much in the days afterwards; we went to the zoo – better species diversity than most, not just the “standards”, but cages need to be a bit bigger for some. The zoo has become somewhat famous for it's eisbären (polar bears) after successfully rearing baby Knut, they've got about 5 total now. We probably liked the cow called Patrick more though. Also, WTF, asymmetric camel.
And we went to the museum with all the trains and so on. The old steam locomotives are fecking enormous, you really have to see them up close to get it. Even the S-Bahn trains (interesting Nazi-era example pictured) are pretty big when you see the whole thing (including the bit you normally ignore because it's below the platform).
There's other stuff there too, eg the brewery, textiles, German computer pioneers, etc., but it's dwarfed by the Munich museum (see next episode).
Otherwise, we just sort of hung out and travelled around Berlin having a look, doing a geocache, eating the food. I like Berlin, it'd be an interesting place to live for a while.
