It's family vacation time, and I've taken the kids back to where I grew up — a small plot of land off a dirt road in Kansas.
For my city kids, this is supposed to be heaven. There are freshly laid chicken eggs to gather, new kittens to play with and miles of pasture to explore.
But we're not outside.
I'm sitting in my childhood bedroom watching my 7-year-old son and his 11-year-old-cousin stare at a screen. The older kid is teaching the younger the secrets of one of the most popular games on Earth: Minecraft.
