Years ago driving my '51 half-ton home at night with no seat belts, I swerved to miss hitting a dog, ran into the opposite side ditch and rolled it. When things stopped moving, I found myself laying on the roof staring up at the floor. As I struggled to get a door open, I began to feel something burning and realized it was battery acid dripping on me. I got out real quick and started ripping off my clothes which was somewhat of a surprise to the folks living nearby. Never the less, I came away with only a few acid burns and some bumps and bruises. The next day a friend and I came back, rolled Old Paint back on her wheels, poured in a quart of oil and drove her home. God, what a truck.
