Where have you hit some really high speeds in SoCal?
My big descent is Mt Baldy Rd. My top speed on the top section so far is 51.8 MPH. From Baldy Village down to Claremont, I've hit 48.x MPH on several occasions. I once hit 49.7 MPH descending Scripps Poway Rd (going west).
Places where I've hit speeds up to 46.x MPH are too numerous to keep track of. I can't think offhand of other places where I've cracked 47 MPH.
Any favored places to hit some really high speeds?
