No, that's my new AO with the mini Eau Rouge. Hahah...I remember that turn you speak of. When I first went to University, "32 people have died over the last 3? years" By the time I left it was 16. But that, IIRC, the sign is at the top of the mountain going back down to the valley and is proceeded by a left hand turn (going towards 'Nam, confirming your analysis) but I think to the side was...well...ARMCO only and "air." Been way too long (30+ since I drove that). Next I go up there (maybe this year) I'm still taking 71.
How I didn't crash the car I'll never know. Passing cars....game on..that one long straight strip that going south you could get a small push with a 50 foot decline and I'd suck up 2-3 cars

. The 3-lane part... that was a war zone wasn't it?
Looking back...I was an absolute dumb fuck. But, fortunately, while the speeds seemed high then, today I'd not blink as I have MUCH MUCH better skills (and car). I knew it like the of my hand too. I drove 71 from Fort Smith to 270 to Hot Sprigns not long ago and yikes I was RUUUUSTTTTY!!
