Has this ever happened to anyone- I went to Boston with my family, and I had my camera strap around my neck with my 70-300 mounted, and I was getting some great pictures and just having a good time in the New England Aquarium area. Well, I looked down and one side of my strap was loose from the hook on the camera. I don't see how this could happen on its own, because it's got the buckle that you have to weave it through, and it's got the slider, also that just holds the two pieces of strap together. It's never come off before or since, but my strap was dragging on the ground before I noticed... Does anyone think it could have just come loose?
