Bounce, with an incredible ability to remember Texas back roads, replied: Heading from East (Terlingua) to West (Presidio) there is a section that can catch riders unawares. Running that way, an observant rider will see a crest in the road and nothing past the rise. More than one rider has been a little less than prudent and not scrubbed off a lot of speed before heading into the unknown. On the other side of the crest is a quick elevation change (hence the lack of visibility) along with a hard left (I think it's also off camber). So you're in negative Gs while also needing that lost traction to try and cling to a hard left, off-camber turn.
It's about 2 miles east of Lajitas.
