But . . .
I remember a Mystery Hill near my hometown in Massachussetts. Stop the car, put into neutral, and you apparently roll uphill. Illusion?
The traffic jams sometimes got so bad the town fathers eventually directed the road department to grade the hill down. End of mystery.
Regarding the two disabled kids: weak though it is, our bodies do generate a magnetic field. Suppose theirs were somehow distorted but the field in the building boosted them?
Fascinating once again, Billy. I visited Mystery Hill in NC as a child with my family. It was weird and a little terrifying. See what a wimp I am/was?
Anyway, our daddy told us 5 kids that it was just a house built on a steep hill and it was just a trick. That is what I thought all my life. He was my daddy after all.
Now I know better.
