Someone called 911. For what ever reason a life flight helicopter was then called and picked him up and took him to a local county hospital. He woke up there a few hours later. After they had already ran all kinds of tests. They had a large list of all the problems from busted spleen, broken bones, head concussion, etc.
After a day of rest in the bed, the only thing wrong was a sore ankle and some deep scratches on his face. He checked himself out and we went and drove him home. They sent a bill of $16,000 the next month to him. He asked why it was so high since the only thing they did was give him a helicopter ride and a bed to sleep in (none of which he consented to but of course hard to consent when you are unconscious).
He sent them a check for $16 which was the minimum amount required. He fully expected to pay $16 per month for the rest of his life, but they never sent another bill and he never asked... That was 15 years ago.
