Its been many years but probably one that's more memorable are riding Palomar Mtn on my Fuji S12-S, geared for touring. Last time was way back 1980s when there were less motor vehicles and canyon Joe's on their crotch rockets. An excellent grind, guessing 5 to 6% grade.

Could only imagine the traffic these days but if I resided nearby, still irresistible and probably would fit it into as an ideal workout.
