My grandfather was an engineer. For my 12th birthday, my dad drove me 2.5 hours to the coast where his dad's train yard was. I had no idea what was going on... Until we got out and my grandpa stuck his engineer hat on me and invited me up into the drivers seat. I drove that train about 2 miles down the track and backed it back into it's home. What a fanfukinstastic birthday present! I've loved em ever since.
