Creating a Monster

Ok , so it all started innocent at first.

My son , not yet three, well truth be told I see ALOT of me in there, his looks thankfully he gets from his mother but the rest is all me. So with that being said I can completely relate when I see him get into trouble, not able to calm down all that energy, that need for a rush.
So we have started playing this game called "speed racer". Was a great game till mom found out. The game began harmlessly by me putting him on his big wheel and letting him free fall down the driveway into the street with me watching at the bottom of the slope. (We live at the end of a very quiet culdesac so the only true danger was him tipping over). Then I had the idea, lets tie him to the back of the bike and I can tow him around a bit. Now it was fun and hey I was getting a bit of exercise in the process.
Now the part where I realize I am in trouble. Everyday for the past 2 weeks when I get home from work .... there he is ... helmet in hand, sitting on the porch ... waiting like a tiger in the weeds for his victim, me, he pounces as soon as I get out of my truck... "Daddy.. its tyme for speed wacer". I get the bike out hook him up and he hones his skills whipping behind me like a professional water skier. Thus far we have only ran into 2 parked cars, 3 shrubs, and there was the unfortunate puppy accident.
