Now you can track your Google Maps searches on Google Personalized Search, for future reference. Since Google already has "Saved Locations" within Google Maps, I think including Google Maps in Google Personalized Search is more or less a repetition. Google Search History now tracks your Web, Images, News, Froogle, Video, and Maps searches, as well as the Music you listen to while GTalk is running.

Google users who have enabled Personalized Search, can access their history through the 'Search History' link in the upper right corner of Google Maps.
