Many new people who try out a congregation make the decision as to whether they are coming back before they are seated in the worship center. Many turn-off signs are in the parking lot. If there are obvious visitor or guest parking places near the worship center that is a good sign. If instead there is a whole row of senior adult or handicapped parking next the building that may be a bad sign depending on the demographics of the visitor or guest.
Congregations desiring to transform need to keep this among other things in mind.
