I just discovered a nifty use of a new Google feature called My Maps. This allows you to create an interactive annotated map of any area. You can put icons at various locations and enter descriptive text and photos for each. I created one for a buyer client showing the locations we were going to see during our outing. Gives a great overview of the home locations relative to each other, and in this case proximity to ASU where their daughter would be attending. Here's a link to the map I created. I'm sure there are even more creative ways to use this, such as creating a map of your listings including photos and descriptions.
