The "Circling of the Montanas" Rally at Quartzsite is approximately 5 miles North of the town of Quartzsite off of SR 95 and East on Plomosa Road.
From SR 95, go East on Plomosa Road 2.8+/- miles. Turn left, North, when you see the "Montana Owners Club" sign. (see picture below) Stay on the road in the middle......look for many trailers with "MONTANA" decals on the side.
For you GPS buffs, the coordinates to the wagonmasters domain are as follows:
