I don't remember a tunnel of love ride......just a boat ride through a "haunted house" that wasn't scary. And there were like 6 people to a boat, so how much could you do anyway?
the Old Mill was it and our Jr High and HS school picnics were at Kennywood, so it was definitely where people necked etc. I kept accusing my bro and SIL of necking on various rides this past weekend.
and note the use of the word NECKING... i swear i haven't used it in about 35 years til this weekend!
