As we were on our way out of the refuge, we stopped to stretch our legs near Pool 5. All of a sudden we saw some Sandhill Cranes in the distance as well as several small groups flying in to an area South-westerly across the pool. I had decided to travel light and without a tripod & only my 300mm lens and the 1.4x & 2x converters. This shot was taken with the converters stacked and resting on Les' bag laid on the top of his Subaru -- the equivalent of an 840mm lens. The next time we go to Carlos, I'm taking along my scope with an extra tripod; it's the only way to observe the cranes at the distances they often are from the road. 8x binoculars just don't cut it.
