Better late than never, I guess.

We went to Berlin over the recent long weekend and did something we had never done before in all our travels: we took a walking tour. It was cold as a Norwegian well digger's… It was really cold, and there were about 4 inches of snow, which the Germans are only slightly more adept at clearing than the Belgians, and we near 'bout froze our feet standing in it listening to history lectures. But the lectures were interesting and good, and our guide was knowledgeable, and the group was congenial, and we saw the old city and heard cool stories, and we got a discount with the Berlin Welcome Card.

So now that we've been to a dozen or so cities and are nearing the end of the Big Belgian Adventure, we've decide this is the way to go.
