I was stationed at Holloman AFB in Alamogordo, New Mexico, and rather bored on a Superbowl Sunday (didn't care about football, didn't feel like hanging out with anybody)... so I took off in my '82 Mustang and just went driving. I was just putzing along and found myself in La Luz, thinking about taking the road to High Rolls, since I'd never gone that way before. It was a rather mountainous area, and once I got toward the top of the hill facing the valley, there was a sweeping left curve around the face of the hill - 500 ft drop on the right side, more mountain going up on the left side. Since I was bored, feeling kind of lonely and anti-social, maybe even a little depressed and not paying attention on a road I'd never driven before. I was also moving at a fairly good pace - 65-70mph or so... which was a little too fast for the curve and also the adhesion quality of the brand new Goodyear Eagle GTs I'd just had installed. I lost traction, the back end came around toward the passenger side, and the next thing I know, I hit the embankment (or maybe it was the side of the mountain) on the inside of the curve facing the opposite way I'd just come. I hit it hard enough that it shoved some rocks into and past the beads of the passenger side tires... somehow without losing any air pressure whatsoever - and that was it... no other visible damage. I also somehow managed to stay on the road, completely out of control, and not simply slid off the hill (no guard rail, BTW). Fortunately, there was no traffic either, otherwise I might've crashed into someone coming the other way as I spun out in front of and into the oncoming lane. After that wake-up call, I got out, walked to the edge of where the guard rail should've been, looked down, and immediately had a much better outlook on life. Also, I believe the road was banked in toward the mountain side of the curve, which is probably the main reason for staying on the road. Got back in the car, and started driving back down the hill, fully expecting bent rims, axles, steering, or "something"... but everything was fine.
So, going too fast on a mountain road, lost control, hit an embankment sideways, didn't damage the car, and didn't slide off the side of a mountain to my death. I'd call that a close call.
