What was your strangest encounter while on a hike? Any hike.

Mine was on a 6 mile day hike along Lake Tahoe. I rounded the corner on the trail and met a scuba diver in a full dry suit and re-breather apparatus on his back. He was hiking the 1/2 mile back to where he had parked his car. He looked like a monster from the lost lagoon. My wife & I were so astonished by this that we forgot to take a picture of him. Really weird.
