I have been interviewing Berliners. Some successfully, some not. I have left the recorder on pause thinking it was recording on two occasions... painful lessons. I'll just have to work on getting more interviews.
On the positive side, the wind jammer I made from a tupperware and tights has been working well, and when I interviewed a singer who was performing on Oberbaumbrücke, a bridge that once was a checkpoint, it didn't pick up any noise from the wind.
