Actually there are four of them, north of Cedar, north of Beaver. north of Fillmore and at the bottom of the Scipio grade...
Most everyone behaves themselves with the exception of the occasional Cal. dufus that won’t leave the left lane and the odd Subaru...
both my trucks are pushing 600+ hp with 3.08 gears and are a puzzle to the Cal drivers that we aren’t chained to the right lane and capped at 55...
Actually, California drivers are so used to congestion that they actually are aware their cars come equipped with rear-view mirrors. I did an unofficial "study" during this month's 5000 mile driving trip and decided that Arizonans are by far the absolute worst in that regard.
My other big, big peeve was that apparently MY lonely little Honda CRV was the ONLY vehicle that had something called a "Cancel" button on the cruise control when passing slower traffic and trucks. I never, ever saw even one other driver kick it out to pass, even if I (or somebody else moving faster than they) was in plain sight of them......aggravating pisser, fershur.
