Drive through a community in the Chicago area and you see a lot of signs. One small set of these direct travelers toward religious congregations. Here is one example from Google Street View:

See the small blue sign on the traffic light pole? It directs people to a church a half a mile down the road.

A few observations in seeing such signs:

1. Not all congregations have a sign. Could all congregations request one and then have at least one pointing toward them?
2. The signs are pretty small. How many drivers see them.
3. The signs tend to be posted at busier intersections. Some drives from those intersections are shorter and easier to navigate than others. For example, a driver might see a sign pointing in a direction but it may take a little while before finding the congregation roughly in that direction.

Given that these signs are likely provided as a community good, can their use be improved in significant ways?
