There is a prayer group at one of my churches that prays for about an hour including Rosary, Divine Mercy and other prayers, right after the 8 am Mass. I go to that one when I can. I travel a lot so it’s not always possible.
I joined Fr. Heilman’s online prayer group that sponsors novenas for the United States and ending abortion, etc. Online is very convenient as I can join from anywhere and the meditations are on Facebook every day.
My biggest problem with physical prayer groups is they often seem to change their schedule and the change is not printed on the parish website or bulletin - the group just tells its regulars by word of mouth - so those of us who want to just drop in and pray show up and find nothing happening.
