Using the basic Google.com web site brings Maps and Local listings
Usually I use the maps.google.com site for searching the map and for local business search. But you don't have to. Google has upgraded the ability of the basic Google.com website to find map locations and local business listings.
So here's how it works. You enter a query such as "60611" and Google interprets this (correctly) as a location, and gives you a map.
If you enter a business name, Google will interpret that as a "find businesses" search and give you a thumbnail map with three results. For example, "museums Indianapolis" gives you three choices. You can click on the map to get the full map display.
So next time you want to search for a map or a local business, give it a try on the basic Google.com. If that doesn't work, then go to maps.google.com where you have some refinement choices, especially in the "find businesses" section.
