Heh. I don't remember working on my first tricycle, but I remember adjusting the training wheels on my first bicycle, because I was not satisfied with how my dad had set them up. I didn't go into wrenching mostly because I was always better at taking things apart than at putting them back together again ;). Though I'm a lot better about that nowadays -- why, I only have a single drawer of spare parts left over from taking my Jeep apart and putting it back together again, not a whole garage full! (Well, a single drawer plus a bumper and a couple of rock rails!).
Opinions are like assholes, everyone has one, some peoples stink more than others too. Remember, I can make your opinion disappear, you keep the stink.
