...a time when you got creeped out in a car.
1) Wife & I were heading to the airport at about 3AM, listening to Coast to Coast and some guy was describing in detail an alleged experience he had while working as a long haul trucker where he was out in New Mexico on the highway in the middle of the desert w/ no light & no one around and he purportedly saw an old lady with white hair on the side of the road, hitchhiking. His story was that he passed her in the middle of nowhere and got creeped out, but kept going, and around 10 miles down the road, he saw her or someone who looked just like her hitchhiking. We then had a black cat run across the road in front of the car and we both yelled. Amusing.
2) We were driving out to look for the White Horse of Uffington and it was getting clear that we weren't going to make it before dark. We kept going and there was no one around and this heavy fog descended on the area. So we get there, the light from the headlights are disappearing into the darkness, and she says, "I'm going out there to see if I can see anything." She goes out a short distance, turns around with this look of horror and hauls back to the car and says, "There's something moving out there, let's go back tomorrow, when it's light."
3) Near misses, accidents, etc. Those aren't amusing.
