I was watching Granite Flats, and at the end of the header they show an old playground merry-go-round. It was upon a similar apparatus that my older brother broke his ankle, the first year we lived in Hyrum. I was in second grade, and he was in fourth, so it would have been 1964, late autumn.
I wasn't there, but this is the story I was told. He was playing on the merry-go-round with a group of children. Some how he got pushed off and his leg got caught underneath the merry-go-round. It twisted his leg and broke it at the ankle. I was introduced after school as I saw him with a big cast on his leg.
He was pretty popular with letting people write on his cast. He also got lots of special attention.
