How Can You Throw Rocks With Your Mittens On?

"You'll Put Someone's Eye Out!"
And equal time for the ladies:

Read how Mittens' first encounter w/ Mrs. Mittens went. (See the section "Mitt Meets Ann.")

The Beatles and the Rolling Stones were playing on 45 rpm records. Mitt saw her across the room. He remembered that when he was a Cub Scout in elementary school, he and some other scouts saw Ann riding a horse bareback across a railroad track.
"What do Cub Scouts do when they see a little girl on a horse?" Mitt says now. "We picked up stones and threw
them [at her]."
Years later, at Cindy White's party, Mitt thought, "Wow, has she changed!"

(Emphasis added.)

Was this a part of anyone else's Cub Scout experience?

Or just Michigan in the '50s?
