Mexican biker rings.....

I just recently found this in my moms garage..... We just moved to California, 1972.... It was early July, right after my birthday.... My mom announced,"we're going to Mexico tomorrow for your birthday!" Yeah, right, for my birthday....  Well we all loaded up in the station wagon, Alice, my moms friend that talked her into moving to Cali before "the boys turn into their father" (alot of good that did), her husband Gary, my stepdad, Russell, some guy that seemed to always be staring at my stepdad but when no one was around would have his hands all over my mom, Alice's sulky teenage daughter Jane, that I constantly stared down her top,(she knew) my brother and myself. We flew down the coast to the border, the adults smoking and drinking and getting louder by the mile...... We rolled into the original Rosarito Beach Hotel before sundown and the place was going off. we sat in the pool while the warm Baja night was closing in on us looking in at the grown ups getting completely crazy, singing, screaming, knocking everything off the tables to dance on them.... The next morning was total shit... Everything I said was wrong and I was in the way no matter where I was..... I couldn't  say a word as we drove towards Tijuana with the ADULTS( I use that word loosely) looking for a bar to lick their wounds..... We were given $20 to get lost for a few hours. We roamed the shops on the main drag, I was searching for the biggest switchblade I could find... Everywhere were surfers and bikers going in and out of bars and shops.... I watched these two groups, what they wore, how they acted, what they said..... A lot of the bikers would buy these rings, their hands were solid with them...... After I went in a couple dozen storefronts a shopowner said," hey chicken legs, don't be a pussy, buy something!" I was kinda scared and wished one of those adults was with me so I just pointed to the first ring I saw...... There were so many rings way cooler but I just wanted to get out. The ring was $7 and he gave me $4 change back outta a  twenty. " get outta here, I got business! Now you're a gringo biker?!" When we were driving home I reached into my pocket and pulled out the ring, it was way too big.... I had to wrap tape around it to make it fit.... A week later Alice's husband committed suicide by hanging himself. Here is the ring....
