Provide sub area selections for large metro areas

[ajsmithd]

Please provide sub area selections for the large metro areas such as SFBay or Los Angeles. for example the SFBay area is divided into North Bay, South Bay, Peninsula, East Bay, and San Francisco areas on the Craigslist site. It would be better to allow them to be selected individually on this site because there would be too many responses/ads for all areas combined and most marketers would want to only focus on one of the areas. Thank you for this great service.
