wild ride down a 175feet bluff

WOW!!! Sure glad you're OK...relatively. That must have been a wild ride. Now you know why your mom used to tell you to always wear clean underwear - may not have been after that ride! LOL
Betcha you didn't say, "That was fun. Let's do it again."
Again, glad you're OK. Now it's time to go after the county for both $$$ losses, towing, and medical expenses. Like it was said before, they may not want to pay but that doesn't mean they shouldn't.
