We had a short tunnel ahead and had discussed before that going through a tunnel without a light was an issue but, since the tandem has a powerful headlight, that could be made to work. I decided that holding the frame, taking a photo and spinning the wheel all sounded a bit of a challenge so I volunteered to drive through the tunnel. Shane had a trial run of setting it all up, then as I was lining up to go in I thought I would like a shot of the approach. Luckily the entrance was quite a wide target. I could see all the way through easily, but that is less obvious in the photo.
