Whether you are traveling, have moved to a new area, or would like to attend a Church service for the first time, try the Meetinghouse Locator. This upgraded program provides many user-friendly options to help you find a chapel near you.
The locator uses both Google Maps and Microsoft Virtual Earth. I haven’t seen any other website to use both.
