Yosemite National Park, CA
While driving back to our campsite one evening at Yosemite National Park, it started pouring...and then hailing. All the while the sun remained out, and I told my wife to start looking for a rainbow. Finally, we came around this bend and BOOM! I wanted to capture that exact scene, but as soon as I walked back up the road, every tourist leaving the park started stopping in the middle of it. I realized I was tipping them off standing there with my camera, so I stepped off the road behind a tree. And sure enough, they started flying right past & I got the shot
