Years ago driving back from Sacramento to Monterey I went over Pacheco Pass, and I saw a small car broken down on the side as I was coming down the hill. There were kids in the back seat playing under a sheet, and there was a lady on the passenger side with the door open.
I felt bad for not stopping and was giving myself a hard time telling myself if I saw anyone else (fat chance) that I would have to stop when suddenly I saw a priest walking down the right side of the road. He was wearing a black robe, and it reminded me of that character from SNL back in the 80s, Father Guido Sarducci. I figured since it was a priest there was no question that I had to pull over and help.
When I pulled up he looked old with his face all wrinkly and burnt like I remember the old homeless guys living under Monterey Wharf looked, his clothes (robe) looked tattered like he had gone through some serious roughness, and he looked very mad. When I asked him if he needed help he mumbled something, but I couldn't understand. I told him they might hassle him for walking along the road, and then he turned to look right at me and spoke clearly: "So you're trying to help me?"
I told him I had thought he might need a ride, and he asked me if I had seen a woman walking, but I told him no. I thought this was strange since it was an odd place to take a walk, but I wished him luck and started again onto the road. I looked back in the rear-view and didn't see him, though. I remember thinking that was a little strange because there was nowhere out there to hide, but I just kind of ignored it until years later when a friend posted an article about ghosts in Central California and it described the ghost in black robe up on Pacheco Pass and it hit me.
After a bunch of research, I found a forum where people were talking about experiences they had, and several of them described a small car on the side of the road with boys playing in the back seat under a sheet and a lady getting something out of the passenger side.
