You should join some leagues now that you are playing again!
I was a high school doubles player, and love playing when I can, but it is rare (since I don’t belong anywhere and don’t have a lot of tennis playing friends). Plus, I now usually play golf over tennis when I have the time.
I will say that tennis seems to be dying and being totally replaced by pickleball. I have played pickleball some, and it can be fun if you are playing with some good athletes. Otherwise, it is more of a social thing.
