Thinking about the interstate bridge washout in CA reminded me of an event many years ago.
I was driving through the empty desert late at night, way too fast,in a pouring rain, on my way to NM to do some skiing. Way up ahead there was a flickering oil flare on the side of the road,(i said it was a long time ago..) and just as it occurred to me to wonder what that was all about, the road dropped away into a wash-which had a 20 foot wide torrent of water going through it. Too late to stop, so I accelerated going down into it. For the first bit the car sort of skidded on top of the water, then dropped in and sent a massive wave of water up completely obscuring the view ahead. No point to backing off, so kept the throttle on hoping to make it to the other side. The funny thing , just as the car broke onto solid ground sending a deluge of water everywhere, I looked left and saw a car parked right on the edge of the flood, with a guy inside smoking a cigarette- the bow wave crested completely over his car, and to this day I would swear he had his window down. I thought it best not to stop...
