Remember when you were simply a child and you used to build things? That little engineer in you wanted to innovate and create. What was something that you have created back then and still hold it high to this day? I remember my early teen years and Airsoft was a big deal to us. We got tired of roaming everybodys house and shooting the place up. So we went into the woods and dug these massive trenches! They were about 5ft deep and spanned on for several yards. We made branching paths, bunkers, pill boxes, tunnels, and even roofs. Great times! Took several months to finish.
