There's a local association called SCSSA that once in a blue moon has a 40 tourney.
A few locals have tried 40/50 Seniors as well but those faded away due to low participation.
As for 50 and up there are leagues here and there plus SCSSA.
USSSA/GSL has 50's and up too but when there's not enough 50 and ups they'll mix them with the 40's and that's it.
By the way, a very Happy Thanksgiving to all of you and your families.
