This is a heavily patrolled highway between Cottonwood and Sedona, commuters get pulled over daily. There is a sudden and unrealistic 10MPH drop in the speed limit before one reaches the Mobile Home park while driving North, where the DPS car lies in wait…Going South toward Cottonwood at Lower Red Rock Loop Rd, there is very wide curve which dips down and it is near impossible to maintain the 55 MPH speed limit, and I see motorists pulled over several times a week for going too fast. Beware!
