Using a Sony Cyber-shot 6.0, don't ask me why?

I don't like wearing jerseys, only on forum rides to a carry the camera. When I ride with my wife I know it's not a problem to stop at a park and refill the water so I only carry one large bottle.

I cut a watterbotle in half, or more like 75/25. I use it in the seat tube water bottle cage to carry the camer. I slip a plastic shopping bag inside the cup like fixture I created to soften the ride for the camera. Also keeps it from jiggling and holds it in place!
