In keeping with the fun of the pages below you will find the official brokenaxle.com trail rating system.
Many thanks to twojeeps for his dedication and years of study while developing this sophisticated method.
Further we would recommend to whomever should be doing it that these signs from henceforth be placed on all trails to alert drivers to the trails difficulty.
Credit where credit is due.  Some of these descriptions were borrowed from the Red Rock 4 Wheelers web site, Thanks guys.

"We can hardly improve on the original description written a few years ago by Jack Bickers: "with driving by World Class Yahoo Jeepers not much concerned with vehicle durability or personal safety." It is common to have as many as 10 percent of the vehicles experience major mechanical failures (gears, axles, driveshafts) on these trails."
= BIG GNARLY

FUN but tends to break small and large parts at a regular intervalls.  NOT the place to be if you like your paint job.  Seat belts and nerve calming agents recomended.  Spotters & recovery equipment mandatory, EMT training helpful (both human & vehicle) CW McCall said "you don't have to be crazy to drive this road but it helps" = INSAINE
