How Do I get City State Zip in MVC 3 URL Route without writing a controller for every state and actions for each city

Question

I have the need to have the urls in my bosses application look like:

http://domain.com/Texas/Dallas/72701

However, I don't want to write a controller for every state and an action for every city.

routes.MapRoute(
"DrillDown", // Route name
"{controller}/{action}/{ZipId}", 
new { controller = "State", action = "City", ZipId = UrlParameter.Optional} // Parameter     defaults

Can someone help me write a pattern for the routes that will accept State/City/Zip without destroying the ability for me to have regular routes with controller/Action/Param ?

Looking all over and can't find any direction.

If you are able to add one more path segment to the domain path you could get this to work pretty easily

routes.MapRoute(
"DrillDown", // Route name
"Location/{State}/{City}/{ZipId}", 
new { controller = "Location",
      action = "DrillDownAction", 
      State= UrlParameter.Optional, 
      City = UrlParameter.Optional,
      ZipId = UrlParameter.Optional
}

Which would give you urls in the form: http://www.domain.com/Location/{State}/{City}/{ZipId}
