Finding stuff with google maps

Here are some very cool applications for Google Maps:

• Cheap Gas for a given area


• Housing for sale/rental


• Sightseeing


• Local search for things like "Starbucks"

I think that another good usage of google maps would be to show garage sales similar to the housing sales/rental (that uses Craigslist for its datasource). Then Google should allow you to select a bunch of locations on their map and give you the shortest route to all of the links you have selected.
