Jacks, marbles, jump ropes, and tops were THE toys for girls and boys when I was a kid. We had to improvise to go beyond the norm. We had a 55 gallon drum that was sealed on both ends that we would walk around the yard or try to knock/walk each other off of. We also had an inflated tractor tube that was our trampoline. A favorite of the boys was a pair of boxing gloves. I'm talking a left glove and a right glove. We'd square off, each with a glove, and when a kid got knocked down, we would trade gloves and fight again.
