I totally caught my car bug from my dad. I remember many long nights out in the garage with him when I was younger, learning how things went together and how all of it worked. I also learned how to hold a flashlight steady.
He and I still hang out in the garage when I go home for a visit.
Excellent memories that you are creating now with your son.
"The major difference between a thing that might go wrong and a thing that cannot possibly go wrong is that when a thing that cannot possibly go wrong goes wrong, it usually turns out to be impossible to get at or repair."
-Douglas Adams, Mostly Harmless
