When I was 18, I flew to NOLA in late '77. Sitting next to me on the plane was an older guy who kept talking to me. He said he had a rental car and would drive me to the Quarter (my family was there) since he was staying there too.
When we pulled up to his hotel, he reached over and put his hand on my leg asking me if I wanted to go up to his room with him. I snatched his hand off and told him to **** off. I got out and walked away. A year later, I saw his picture on the news. It was John Wayne Gacy.
