Not sure when it happened, but Glendora Ridge Road (GRR) and Glendora Mountain Road (GMR) are now open. I checked them out today - from Baldy Village across GRR to GMR, then down to East Fork and Azusa Canyon (Hwy 39). A little dirty in some spots but not bad at all. GMR is also open to Glendora.
It was sunny and beautiful (up above the fog and cloud cover) - good ride
