I lived in the hills and of course played Cowboys and Indians, and we all were very good at hiding in the forests. We thought it funny to lose each other and run home to be first at having cookies.
Throwing balls over the house and catching them on the other side, rolling down hills (made me nauseous) and seeing how close we could get to the crick before falling in. Putting a card or something in our bike wheels to make clacking sounds. Rolling a stick against a picket fence. Seeing who could run across old Dutch Holly's bull pasture safely! That was a real test of speed, he had a very bad tempered Jersey bull.
Come to think of it, we were always running around. Not anything today's kids would think interesting enough to get off their butts to do. And I don't remember any of the kids in school being fat but one boy, and was that poor guy teased!!
