Sure. There was a story of a solo camper. He set up his tent in a secluded area. In the middle of the night, he was woken up by a scratching sound on the outside of his tent. He thought it might be a small animal at first, but then the scratching got louder and more intense. He peeked out and saw a pair of glowing eyes. He quickly grabbed his things and fled without looking back.
A family was on a hike in Glacier National Park. They took a wrong turn and ended up in an area that seemed to be filled with an unnatural silence. All of a sudden, they heard a loud screeching noise. They looked up and saw a large, dark shape flying overhead. It was much larger than any bird they had ever seen. The children started crying and the parents rushed them back the way they came, constantly looking over their shoulders in fear.
