Here's my most frightening landscape photo. I hiked several miles in the dark only to end up surrounded by a bunch of alligators in the peak of mating season. I sat there in the dark listening to their grunts all around me seemingly feet away until the sun finally came up with this amazing sunrise. Fortunately the gators seemed far more interested in each other than me that morning.
