Trip to New York and Finland

I have been shooting quite a bit in the last week with my Speedy. We are traveling in New York and Finland and last week we took a nice walk through Tribeca in Manhattan. It's cool how people stop by when I'm setting the camera up. Many people stopped by asking questions and talked about photography and the history if the area. Few stopped to welcome me to Tribeca which was very nice. I had first issue with my old wooden film holders while in Imatra in Finland. When I slid the exposure guard back in, it slipped on the wrong side of the film and once I took the holder out of the camera the shot was ruined. I don't know exactly how that happened or how I could prevent that from happening again. I'm excited to get the rest of the negatives developed though!
