I grew up in Navy Housing off of Mt. Soledad road. I can remember commuting around PB and not seeing other road cyclists in the late 70's early 80's. I worked at Sluggo's in La Jolla right by Wind -n- Sea. Used to ride to work, get off of work and go body-womping, then ride home.
Got t-boned in front of the Mr. Frosty Shop on Garnet Ave riding a 79 Bianchi with all Campi parts. I miss that bike.
