The first time it happened was when my girlfriend and I turned off on a clay road not realyzing it had recently been torn up in preparation for paving. The car immediately sank. Not more than 5 minutes later, three young men in a pickup came by, stopped, got out a chain and pulled us out and left before we could even thank them.
The second time was when my car caught on fire near Douglas Georgia. Within two or three minutes several people had stopped, helped me put it out and one followed me thirty five miles to make sure I got home ok.
My experience in rural Oklahoma didn't end so nicely. Our car sank on one of those wet, red clay roads near a river. We had two small children with us, and my husband and I just couldn't push it out, we were sunk about mid-hubcaps.
We walked to the nearest (also ONLY) house nearby, and there must have been 6 or 7 big, strapping adult males there. We told them our sad story.
"Jis a sec!" one replied, as he went into the house. He returned with two shovels, handed them to us, and they all went back into the house.
Must have been game day!!
