Nice! Almost, about 10 crow-flown miles E of that famous twister. Glendora Ridge Road begins in Mt Baldy and becomes Glendora Mountain Road (GMR) as you travel west then south, paralleling the San Gabriel reservoir before arriving in the city of Glendora. I think I caught 4th gear for a grand total of perhaps 10 seconds during the run, the rest of the time predom in 1st & 2nd. Rode right into that bank of fog in the pic, spent half an hour soaking in it, wishing I'd wiped down the visor with Rain-X. Can't wait to do it again.
Just for the sake of trivia, GMR connects with East Fork Rd which connects to San Gabriel Canyon Road which does, indeed hook up with the Angeles Crest Hwy.
