Yeah, didn't say how fast they were really going, just not 101. Technicality. I'd still wager it was closer to 90 than 50. It's a fun road and even my truck can do better than the speed limit there. My opinion is they have it low so the tourist gawkers won't run off the edge of the highway (1) into the eastbound lane for westbound traffic or (2) into the Colorado River for eastbound traffic [for the most part, the westbound lane is higher than the eastbound, but the eastbound is right along the Colorado River through the canyon.]
