ps,
in the Early 70’s there was a Motocross Track on Garvey, right next to the wash at Rosemead on the south side of the street, directly across from La Victoria, I used to Race there, there was also one in Alhambra on Mission near Fremont!!
I lived pomona. worked elmonte 10 months never went to race track. There was great fats food place up Rosemead on the right. hot dogs and hamburgers. not a chain.
