Hint #2: Goodbye Cobblestone Streets

As promised, here’s our second clue for all of you.  Two days ago, we shared the sad news that we aren’t going to be in Berlin for the summer and offered you two hints.  First there was Martin laying on his back, surrounded by dirty wires.  He was showing you something very important.  The other picture was simple:  clouds.
