glendora mountain road/glendora ridge road/mount baldy road loop.

Very tight better for supermotos rather then sport bikes and wouldn't fun on a cruser but if you want some solitude this is the place. Lot's of magazine photos get shot out here. Lots of cyclist up there be sure to share the road.

At one point during glendora ridge road turns into a one laner but you can see far ahead and there are very few cars out there.
