Growing up on a farm I learned out of necessity. I could never understand why people brought their cars and trucks to a repair shop. Where I grew up Dad fixed everything and I just thought that's what everybody did. Every kid wants to be like his Dad, so I was always anxious to do my own mechanical stuff. Wasn't always right, and may have been cheaper at times to just take it to a mechanic, but that's how ya' learn. Sooner or later ya' figure out the right way to do things.
