In my parish there isn’t a formal Rosary mentioned in either the bulletin or the announcements at the end of Mass, but as you say there could be one that isn’t publicized. We currently have “October devotions” one night a week.Some parishes do have the rosary prayed in the church but they just don’t publicize it. I know several parishes in my area where the rosary is said before the Mass every day.
I’m comfortable with praying the Rosary with EWTN at night. EWTN radio is carried on a station in our area, and I feel as though I’m praying along with other Catholics in my town.
