Thanks for your comments, Mark. I didn't suggest putting stations on the walls because Larry's original posting mentioned windows in the nave and limited wall space. I'd assume if they could have been put there and it was a parish priority, it would have been done. If a parish puts stations in a hallway, that tells me devotion to the Way of the Cross is a low priority. That's unfortunate, but it's an undeniable fact in many places.
People have the knowledge, but lack the motivation, opportunity, or something else.
You are quite correct in saying that an active non-eucharistic liturgical effort helps and deepens participation in the Mass. More often that not, you'll find parishes that treat liturgies as more than rubrics to be followed, that devote energy to music, homilies, preparation, and lay involvement have a livelier prayer life. When people realize an activity will be fruitful for them, they will come. When they feel ownership, they will invest time and effort into making it work. They will bring their children and encourage them. The tradition will be passed on.
