In Nogales, Mexico they have these giant drainage grates along the street that are about six inches lower than the surrounding street and sidewalk. I was walking with my two bodies and I was trying to mount my flash on one body, when I stepped in one of these holes.
I stumbled and fell forward, reaching out with one hand to keep from eating the asphalt, while the other hand kept hold of the camera. But, my other camera swung around my chest and bounced off the ground.
Didn't damage anything but the paint, but my fall and recovery was apparently spectacular because everyone, including a local motorcycle cop asked me if I was okay.
