Summer is a great time to get children involved in outdoor activities. When our children were young, our favorite family vacations were spent in northern Wisconsin. Each summer, we gathered our own four kids and a group of carefully chosen friends and headed north to play. Our plans included swimming, hiking, boating, fishing, game playing, bonfires — just about any kind of unstructured family fun. When we started the Wisconsin cabin tradition, our first cabins were pretty rustic, with few perks beyond running water. Over the years, the cabins have included a few more luxuries. I was determined to keep the focus on interactive play, so the first thing I did when we arrived was unplug the television and bury it in a closet. Initially, the kids were confused, but quickly caught on and took great pride in their ability to go without.
