Stopped in here a few nights ago on the way to Western Village for dinner Res.
Sierra Sid's was a truck stop when I still lived there in 1979-still is but much larger.
A slot advertisement caught my eye so my Daughter and I stopped in to see if they had cards.
My surprise when they made us each one and then showed us how to use them.
On each machine they have the symbol of Sid standing on a coin with coins in his hands. You take your key chain and put the faces
together and up pops your name and points,they stay on the machine and if no money is put into machine they fade-if money is put in
they show your points when you cash out your ticket they again fade.
I have not heard nor seen this system before-have you???? I have thought of a lot of questions to ask since but didn't make it back before leaving.
