Lisa, the kids and I went hiking at Battelle - Darby Creek Metropark after dinner. We threw rocks in the creek and saw the bison. After about 2 miles, five-year-old Luke was cranky. He was getting a cold. So I carried him on my shoulders. The other kids had run ahead to the playground when we got off the trail. Luke believes that rules should be followed and will tell you when you've broken one. Before I even had him on the ground he shouted, "I guess you told yourselves that you were allowed to play on the playground!"
