Change the course of history (momentarily)
I was glad that this was included in the book. While not dangerous per se (unless you’re planning on upping the ante by sandbagging a raging river) it is, to me, one of the great joys of childhood. We had this big dirt pile in our backyard when I was a kid. That dirt pile saw a LOT of action. We were back there every day with our Star Wars figures. I would construct these intricate waterways with rivers, dams, and lakes… would work on it dry for hours, and then the big moment would come when I would bury the hose in the side of the pile so that the water would spurt out from the head of the river as if emanating straight from the aquifer. I was filled with satisfaction as the raging headwaters coursed down the winding path I had built. So anyway, that was loads of fun and I always notice kids are drawn to it. This summer we had the fun of going to Mt. Bachelor in Oregon where we actually got to play in a snow drift in July. The snow was melting and there was a tiny little creek running from the snowdrift and down the mountain. This kid and his dad arrived and this kid just went straight to work building a dam. I could see he was completely absorbed and could have stayed there for hours. His dad, on the other hand, pitched a few snowballs and was ready to get back in the car. I felt bad for the kid, but anyway…. something about dams and creeks is primal and universal. Unleashes the inner workerman or workerwoman in every kid.
