Google Map API Links
(wandering the world... without the packing)

5 Mile Radius Marker w/ Census Data - I use this for the 5 mile tool, since I just moved, I can never remember what towns are around me.

Map My Run - While I use this for tracking my bicycling, it works great for anything... runs, cycling routes, or even commutes to work. You can even upload GPS data to it.

Chicago Crime - While I don't actually live in Chicago, I thought this was a really good use of the API: linking crime stats and Google maps together.

"Metrofreefi  previously offered just lists of free hotspots in various cities, like many other sites. Now, with the Google Maps API, you click the interactive map to reach a state, pull down a menu to get the city, and see exactly where those hotspots are." Copyright ZDnet.

Okay, I lose... this is an awesome site with some great Google Map Mash Ups Listed. I'll keep this page down to just those that I am personally interested in.
