I love photographing on tandem rides, but stoker gets annoyed about stops, especially if we are on a climb. I think if I had the camera in some way easier to access than in the handlebar bag it could reduce stoker resistance. Back in the day, I had a harness that kept my Pentax Spotmatic strapped to my chest with some stretchy straps from which I could one-handedly grab the camera and quickly fire. Don't think SWMBO will allow that one handed action while rolling, but anyway, a quick access from the chest might be a good option. Anybody using something like this? Other ideas?
