I hear ya Howie.... expensive for sure. I still have footage of that wreck somewhere. I'll get my brother to throw it on youtube for ya. lol
I've seen some wild rides a Flammy too over the years, the wall there is flat. The #43 Mini stock flipped there this year in fact.
The wall at DS is the least of their worries.

Thats for sure Jay....the old track is pretty ruff...with the grinding they did,does your head still bounce off the head restraints on entry of turn 3...anyways,i still miss the ride!..

The concrete outer walls at DS were and are the same barriers used on the highways all over NA today. They are designed to do exactly what they do now, keep a vehicle from heading back into traffic after a collision with them. Whether you hit them head on or straddle them, unless you put up a "safer wall" you have one of the best type there is for a 1/2 mile oval.

The enduros being flipped are a combination of changing them to the speed of a street stock, and the number of vehicles. All the flips in enduro I remember involved cars going 3 or 4 wide and getting helped up onto the wall.

Trus, the jersey barriers are good. I think they need to be strightened out though. Theyr'e sitting pretty crooked. (But that'd probably require the same amount of effot and expense as building from scratch, so who knows?)

are the barriers strapped together, one of the worst accidents i saw was a car hits one barrier dislodged it and hit the end of the next barrier,whoops engine on his lap.
