Although it wasn't a pier, the Long Beach Pike suffered a similar pattern of neglect.
I remember it had a risky edge that Disneyland could never replicate. The Pike had a safe (usually) dose of grownup-ness that really caught my eye and stirred my my imagination as a little kid.
My mom disapproved, but my dad taught me how to play pool there. He always had to gently guide me away from the spicy greeting card rack.🤣 I'm pretty sure I could've gotten a tattoo at an early age if I'd wanted one.
They had several arcades with plenty of rigged games. A lot of them were slightly veiled gambling machines.
Dad would buy me a deep-fried corn dog and french fries pulled from the same smoke oil. I thought of that artery clogging oil when I saw him on a gurney following a quadruple bypass. I don't think he regretted his choices in life. At the Pike I got to see the man he used to be. A good guy who changed his life to raise me.
Here's a link to some memories:
