One of my high school teachers had a job at a small college in Montana when he was a young newlywed. One night on a long commute home, he was driving down a lonely road, past fields of corn or grain, when he saw a hitchhiker. This being decades ago in rural Montana, he pulled over to let the guy in without a second thought. The man was dressed in a really old, outdated suit and a big, stylish hat. My teacher said he looked like someone from the '40s. So the guy gets in next to my teacher without saying a word. Teacher asks him where he needs to go, and the guy just points forward. Teacher drives on. The hitchhiker says nothing at all, just pulls his hat down, as though he were sleeping. Then suddenly, he tips up his hat, looks out the window, and says "Stop the car, now." My teacher pulls over and lets him out. The guy stands on the side of the road for a second, and then sprints into the field beside the road until my teacher can't see him anymore (granted, the crop was fairly tall). Thinking this strange, but not necessarily dangerous, my teacher continues driving home. When he checks his rearview mirror a few minutes later, he sees the hitchhiker on all fours like an animal, running (crawling?) after the truck at an inhuman speed. He floors it, coaxing the old truck up to dangerous speeds, and finally loses the guy. Teacher pulls off at a gas station and call his wife, relates the story, tells her to lock up the house. She thinks he's joking. When he asks why she would think that, she says that one of her coworkers told her the exact same story. She thought maybe they were just teasing her with an urban legend. (And that maybe my teacher was in on the joke.) Anyways, my teacher assured her that he was not lying, and she evidently believed him. She vouches for her side of the story, because she showed up to one of our fundraisers and I asked her about it. So yeah, now I just avoid lonely roads in Montana.
