We live on 14 acres and our kids have always loved being outside. Working for a living and having my wife stay home to raise the young-uns, we never had extra money for play stations, or 200 channels of nothing, so alas my kids had to use thier imaginations in thier play. They play with sticks and rocks and a big pile of dirt or a rope swinging from a tree as much as thier regular toys.
They love spending time with thier dad plus they are becoming quite handy. I am so blessed.
