A Quarry? We have millions of those in AZ. If you get horny over going off-road to make your commute shorter, just cut through some deserts. You should know this, you live in AZ. I cut through a desert all the time when I drive to my grandparents. I save about two-tree minutes and the dirt drifting makes it worth more.
I jump off the 303, and take the desert that goes to 163rd.
