We visited a sunstone collection area on Bureau of Land Management land near Plush, Oregon.  (Did we mention that gas is full-service in Oregon?)  You can stop at the store in Plush for directions, and then head 23 miles out to the site.  Only six of those miles are paved, mind you.  Most of the turns are marked.  (!?)  Once you find the place, the sunstone glimmers at you in the sunlight.  They say to visit about a month after the snow melt (that about now).  The water washes the dirt away and leaves the sunstone exposed.  We found many many small pieces (about the size of half an M&M).  We had a good time.  And our odometer hit 88,888 miles on the trip back.
