Church would be my second choice, especially Adoration. How could you not pray, kneeling in front of the True Presence of God?
Sometimes lying in bed is conducive to prayer. I like to reach over to sleeping husband and pray over him. (If he only knew!)
I often pray in the car, while driving, or waiting for people. In fact, I call my car, "the prayer mobile."
I have a "Little Oratory" in a corner of the dining room. I like to sit at the long table and read and pray--Lectio Divina.
I also have a traveling oratory that a Temporary Promised Lay Dominican made. I may post separately about that, but for now, it's a portable shrine that can be put in my purse. I take it out, now and then to say "hello" to Jesus.
Lastly, and embarrassingly, I pray in the bathroom. I was driven to that extreme when I had Cronkhite Canada syndrome. But I stopped it because a Jewish friend said it was rather blasphemous to pray in that atmosphere. However, I took it up again after reflecting upon the conditions Bernadette Soubirous lived in--and she's a saint! Bernadette's windows were prison cell barred windows, looking out upon the village's dunghill. And the Blessed Mother appeared in a grotto where the village pigs foraged!
Actually, I could go on and on. Anywhere and everywhere, that works for you.
