Most users know how to use MapQuest and Google Maps. Linking to these services out of your web site can help users a great deal. Simply navigate to the map you like in these services and copy and paste the URL as a link. Some services don't allow you to save the zoom level but users can zoom in or out as they like.
Use services like these as sub features and don't litter your main content with them. In fact, you may create a page dedicated to these maps.
Do a search by address, zip code or intersection to get in close. Or search by state or country to remain distant.
