My recap of the incident:
I was following carl who has a very capable (near buggy) Scout and kimball was behind me. For those of you who are familiar with five fingers at hollister this hill climb is like that, but without the steps and probably twice as long (a bit of a pucker going up this baby). As we went up carl got to a small curve and stopped as he noticed kimball was lagging behind. I had to stop behind carl (I did not like that). After a couple seconds I asked carl to continue on as there was not much either of us would be able to do on that hill facing upward other than go up and I was afraid if I stayed there too long I might have carb or braking issues that could put me in a bad situation quick (like kimball… did I mention this hill was steep as hell?). We continued way up to the top parked our rigs and started back down to kimball on foot. I was going pretty fast when I heard the booming. Carl said maybe it is his carb backfiring… I said I hope so and we picked up the pace into dangerously fast… man is that a steep hill!! As we continued on to where we last saw him looking down the hill we did not see him. Carl yelled scooter and we heard him yell back “help” (twice) at this point I was looking at my phone to see if I had cell service which I did (thinking 911) as I negotiated rapidly down the hill. Then we saw scooter half under the Scout and half out of the Scout and before a nano second passed carl was yelling are you pinned (again this was a really freaky moment!!). Kimball yelled back no I’m okay and despite what I was looking at I felt a quick sigh of relief. Then he scooted (pun intended) out from under it and I could see he was not only moving normal, but there was no blood or anything. He was even talking coherently despite being shook up and said “it is on fire, but there is water up the hill”. I ran back up to the water that had flown out and started throwing bottles down to carl and kimball… about 6 bottles of water later it was out and the truck was sitting there upside down hissing from air escaping the lockers, etc... It was one pissed of truck! In any case the rest of the evening was spent rounding people up and recovering / getting the truck back to camp. We got him down to the gate yesterday and loaded onto a aaa flatbed.
